µSmart Water Quality Sensors
Each µSmart sensor incorporates a microprocessor providing
and standardised outputs, 16 bit resolution (1 part in 65,000) and
signals: analog, ASCII data output/input via serial interface, pulse,
control & alarm outputs.
Each unit is provided with a multi-point
calibration curve for maximum accuracy across the range.
For the general
description and many features of µSmart sensors see near the top of the
"Environmental Monitoring" page (link below).

µSmart sensors are intended
for permanent or semi-permanent installation, and connection to a data
logger or computer.
An LCD display box can be attached.

Water Temperature Sensors
A fully sealed and immersible sensor for water monitoring applications.
The sensor is mounted in a stainless steel body with copper heat sink to
monitor water temperature.
The TW1 is available in 2 sizes: length 257 mm/OD
37 mm, and length 220 mm/OD 32 mm.

with or without motorised wiper with various ranges. NTU=Nephelometric
Has two parts: the Sensor unit, joined with
a short cable to the Electronics unit, which gives the µSmart
Both units are suspended in the water. The 2 small sensor
windows are off centre on the lower end of the cylindrical sensor housing.
A wiper is attached to a central rotor, which is preset to rotate once every hour
The wiper is used to clear algae, etc, from the sensor, and is recommended
when the sensor is immersed for more than a few days.
The wiper material can
be easily replaced.
The standard sensors are rated to 30m depth (optional
100m can be supplied).

Oxidation-Reduction Potential, range
±750mV. Need over +600mV to kill bacteria.
Oxidation is a process in which a molecule or ion loses electrons.
Oxidation is always coupled with reduction, as another molecule or ion picks up
The oxidizing agent gains the electrons. Data: please request 02 9481 7420

Price includes 5m cable. Specify
cable required at time of ordering.
You need enough 8 core vented cable on
the sensors to bring the cable above the highest water level. It is terminated
in a vent housing.
The vent housing is part of the overall price of the unit.
The rest of the distance to the logger is run in three core cable.
