Neon Remote Terminal (NRT) with Cellular or Satellite Transceiver

The Neon Remote Terminal (NRT) combines a data logger with either a duplex cellular or satellite transceiver. The NRT is designed to automate collection of remote data from environmental monitoring, industrial measurement, Neon Satelliteand utility metering sites. Neon Terrestrial NRT It connects to sensors in the field, collects readings from the sensors, and transmits the collected data to a central server. Fully bidirectional communication is possible via the Neon server - data can be collected directly, and the NRT programmed, from any internet connection on the globe.

Analite 495 Turbidity & Temperature Recorder

Analite 495 Turbidity Temperature Recorder

The 495 Recorder is functionally equivalent to the Analite 395 turbidity probe, but includes a temperature sensor and flexible data logger, packaged in a self-contained stainless steel cylinder that is easy to set up and download via the RS-232 PC interface. This microprocessor based turbidity logger is designed for monitoring and logging applications where turbidity levels of up to 1,000NTU may be encountered. To maximize resolution, user selectable ranges of 40NTU, 100NTU, 400NTU and 1000NTU are available. The 495 uses nephelometric 90 degree optical retro-scatter technology to ISO-7027 specifications. A newly implemented differential measurement technique with sample and hold provides enhanced performance at low turbidity levels, and extremely low zero drift. The sensor uses a unique modulation technique that ensures almost total rejection of ambient light, and the integral wiper assembly keeps the lens clear of sedimentation build-up and bio-fouling.

Solinst Submersible Level Temperature & Conductivity (LTC) Recorder

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. The conductivity sensor is a 4-electrode platinum sensor, with auto-ranging capabilities. Using standard Levelogger Software, it displays conductivity, temperature, and temperature-compensated water level. Memory is non-volatile and stores up to 16,000 sets of readings. Measurements are linear, in any interval between 5 seconds and 99 hours.

6536 Conductivity & Temperature Recorder

6536 Conductivity & Temperature Recorder

The 6536 Water Conductivity Recorder is a complete measurement system suitable for permanent field installation. Graphite electrodes, combined with zero potential measurement technique, maximize stability and reduce effects due to algae growth and other water pollutants. Three built-in ranges allow the one instrument to cover a wide range of conductivities. Autoranging means the instrument works at its optimum resolution throughout the operating range. This enables monitoring of saline conditions while still accurately measuring flushes of fresh water.
