Solinst Levelogger Gold Level & Temperature Recorder

The New Levelogger Gold represents the next generation of discrete water level & temperature dataloggers. With no vented cable, the sealed design combines a datalogger, built-in lithium battery, pressure transducer and temperature sensor, in a small, minimal maintenance, 7/8" x 6" (22 mm x 154 mm) stainless steel housing.

It can be suspended on a simple wire line, or connected to the surface with a direct read cable (for downloading of data and/or reprogramming without removal from the water). More details at Solinst Levelogger Gold

Solinst Submersible Level Temperature & Conductivity (LTC) Recorder

The LTC Levelogger Junior logs conductivity, as well as water level and temperature. Like the Levelogger Gold and Junior, it is easy to transport, program, deploy and retrieve data. It combines a datalogger, 5-year battery, pressure transducer, and temperature and conductivity sensors within a small stainless steel waterproof housing, 22 mm x 190 mm. Memory is non-volatile and stores up to 16,000 sets of readings.

Testwell Water Level Meter

For measuring the depth of water in wells, boreholes, and standpipes, the Testwell Water Level Meter is accurate to 1/100 ft or one millimeter.

The meter uses a choice of probe designs, attached to a permanently marked polyethylene tape, fitted on a well-balanced reel. It is powered by a standard 9 volt battery housed in an easy-access battery drawer.

Solinst Model 102 Laser Marked Water Level Meters

The Solinst Model 102 Water Level Meter is designed to measure groundwater levels, especially in small diameter tubes and piezometers or where a flexible cable is needed to snake past an in-well pump. The cable has a heavy-duty jacket and stainless steel coaxial conductors for strength. Permanent markings are precisely laser etched on the cable every 1/100 ft. or each millimeter.

Testwell Oil/Water Interface Meter

The Testwell Oil/Water Interface Meter is the first small diameter (7/16", 12mm OD) Interface Meter which detects floating or sinking hydrocarbons down to 1/2 mm or 1/200 of a foot. A 5/8" (15mm) diameter stainless steel probe, which has all of the features of the smaller 7/16" diameter probe, is also available.

Testwell Oil Water Interface Meter

The Testwell Interface Meter measures both LNAPLs and DNAPLs with a pressure proof stainless steel probe.

Solinst Model 107 Temperature Level Conductivity (TLC) Meter

The Model 107 TLC Meter is ideal for profiling conductivity and temperature in wells and open water and for salt-water intrusion, contamination and salinity investigations. The TLC uses an "intelligent conductivity" sensor with platinum electrodes. The sensor is attached to Solinst flat-tape, accurately marked every 1/100 ft or every millimeter, available in lengths up to 300 ft or 100 m and stored on a plastic reel.

Waterra 12 Volt Submersible purging and Sampling Pump

The new Waterra 12 Volt Submersible Pumps can lift from 25 to 70 feet and are designed specifically for well purging and sampling procedures. The high performance DC electrical motor is suitable for continuous running - no cool down required (up to 5 hours), and the long life motors last up to 100% longer than competitors' models.

Four models are available: the single stage WSP-12V-1 with 25 foot lift and 35 foot power cable, the double stage WSP-12V-2 with 40 foot lift and 60 foot power cable, the three stage WSP-12V-3 with 55 foot lift and 70 foot power cable and the four stage WSP-12V-4 with 70 foot lift and 80 foot power cable.

All four pumps are supplied with alligator clips and adapt to 1/2 x 3/8" low-density poly tubing. All of these pumps can greatly speed up the process of purging and sampling monitoring wells, especially if dedicated installations are used. These pumps are complete and ready to use, and an optional on/off switch for the power cable allows the user to switch pump on and off without having to disconnect from power supply.

Solinst Peristaltic Sampling Pump

The Solinst Peristaltic Pumps is designed for vacuum pumping or pressure delivery of liquids or gases. They are ideal for sample removal from shallow wells and surface water.

The mechanical peristaltic operation is effective to depths of approximately 33ft or 10m at sea level, limited only by the suction lift limit which varies with elevation.

The Solinst Peristaltic Pump has variable pumping rates and can be fitted with 2 different sizes of silicon pump-head tubing. With the 3/8" OD (10mm) tubing the pump delivers a sample rate as low as 40 ml/min and up to 900 ml/min. If the 5/8" OD (16mm) tubing is used, it delivers from 120 ml/min to almost 3.5L/min.

The Solinst Peristaltic Pump is very compact and easy to use. It measures 13" x 5" x 6-1/2" (32cm x 13cm x 17cm) and weighs only 8lbs (3-6Kg). The metal case is extremely robust, water resistant, and has no grates or openings. A handle and easy-access controls on the top of the pump make it perfect for field work.

The pump operates using any 12 volt DC power source (battery) which can supply at least 3-5 amps at maximum draw. More detail at Solinst Peristaltic Pump

Redi-Flo2 Portable AC Purge & Sampling Pump System

Redi-Flo2Designed for portable, efficient and reliable sampling of wells for ground water purging and monitoring, the Grundfos Redi-Flo2 has taken the complex process of ground water monitoring and made it simple. Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump. The Redi-Flo2 is designed for both dedicated and non-dedicated sampling installations.

1.5", 0.7" Waterra Clear PVC EcoBailer

Geotech Disposable Sample FilterThe Waterra Clear PVC EcoBailer is an eco-friendly product that is heavier than conventional weighted bailers without the addition of bulky and costly weights. A better weight distribution allows the EcoBailer to sink straighter and the efficient valve design makes it the fastest sinking bailer on the market. For a super fast sink rate you can utilize the 7/8" stainless steel weight that can be easily screwed onto the bottom spout of the bailer and reused when needed - no other bailer offers this innovative reusable weight system. Made of clear virgin PVC the EcoBailer allows you to inspect your sample while still in the bailer.

These bailers are designed with a special valve and valve seat to provide more positive sealing and less clogging when removing the bailer from the well. The 1.5" (1 litre capacity) and the narrow 0.7" (200 ml capacity) bailers, come with a longer bottom emptying spout that helps prevent silt from interfering with the check ball and causing potential leakage. They also assist in collecting non-aerated samples from the valve end of the bailer, which is ideal for VOC sample collection. Waterra Clear PVC EcoBailers are easily adapted to the Waterra FHT-45 Disposable Filter for collection of samples for metals analysis directly from the bailer.

Inline Disposable 0.45 Micron Filter

The Waterra FHT-45 offers the most surface area available in capsule type filters today. The unique open pleat geometry and 700 square cm surface area provide the maximum media exposure while ensuring that even with the most turbid samples, you will not lose filtration media to blinding.

The Waterra FHT-45 uses high quality polyethersulphone 0.45 micron filter media that offers excellent particle retention above the target micron size range, and the high void volume of this media also helps prolong media life. It also offers the user greater flexibility by providing a compound inlet - it has both a 3/8" threaded nipple and a 1/2" hose barb allowing the filter to be attached easily to a variety of pumps and tubing sizes.

The new medium turbidity Waterra FMT-45 has all of these great features as well, but with a reduced surface area at 300 sq. cm. These filters provide an economical alternative for lower turbidity sampling, when the highest possible capacity is not required.
