Phionics
Submersible Water Quality Transmitters - Conductivity, Dissolved
Oxygen, pH, ORP(Redox), Temperature
 The
Phionics series of submersible water quality transmitters have
an integrated preamp and an isolated 'true 2-wire', 4-20 mA transmitter.
Two independent channels can simultaneously transmit either a
conductivity, dissolved oxygen, pH or ORP(Redox) signal, as well
as, an optional temperature signal - two wires for the water quality
parameter, and two wires for temperature. More

Hanna
Combination Double Junction AmpHel pH and ORP Electrodes
 Hanna's
latest additions to their range of combination pH and ORP electrodes
incorporate over 20 years of electrode manufacturing experience.
These advanced electrodes feature a combination Ag/AgCl sensor
& reference system, and proven flat tip technology for superior
field and in-line performance. Hanna's flat tip electrodes have
shown significantly less breakage than bulbous electrodes. More

Oxyguard
Dissolved Oxygen Sensor
 The
robust construction and simple design of the Oxyguard D/O probe
make maintenance and servicing easy. It uses a strong, easy-to-clean
and easy-to-change membrane in a screw-on membrane cap. The probe
design uses a galvanic cell with built-in temperature compensation.
The probe requires no power, and produces a millivolt output proportional
to the oxygen present in the medium in which it is placed. This
millivolt signal can be inputted to a data logger such as the
Starlog via a two core cable. More

6507
Thermistor Temperature Probe
These economical
thermistor temperature probes are designed for many applications
of temperature measurement like air, water, soil, snow, ice, etc.
They are fully
sealed and can be used in fresh and sea water to a depth of 2-3
meters. The thermistor temperature probes use a Negative Temperature
Coefficient (NTC) thermistor as their temperature sensor. More

Analite
9000/9500 Turbidity Probe
 With
a very small viewing distance, the 9000 series is ideal for
applications with limited water such as small low flow creeks.
The 9000 non-wiper version is designed for applications with
minimal bio fouling such as fast cold running water, or short
monitoring deployments. The 9500 version, with its integral
lens wiper assembly, is designed where bio-fouling or sedimentation
buildup is likely. More

OBS-3+
Turbidity Probe
 The
OBS-3+ sensor measures suspended solids and turbidity by the optical
backscatter method (ASTM 6677). It features a compact micro probe
that responses almost linearly over a 1000-fold change in sediment
concentration (SSC) and turbidity, which is advantageous in natural
systems where concentration can vary widely. More
