Specifications

Probe

Construction: The sensor consists of three stainless steel rings mounted in an epoxy tube.

Size: (L x W x H) 89mm x 25.4mm x 19mm

Weight: 120g (with approx. 1 metre cable)

Maximum Cable Length: 300m. It is recommended that the sensor is ordered with the desired length to avoid any jointing problems; for ground water

applications it is also recommended that an optional (80g) weight and cable grip are ordered for cable lengths over 30m.

Depth Rating: Maximum 300m.

pH Range: Solution pH of less than 3.0 or greater than 9.0 may damage the housing.

Cleaning: Nylon brush provided

Conductivity Sensor

Electrodes: Passivated 316 stainless steel with DC isolation capacitors.

Cell Constant: Individually calibrated. The cell constant (K

c) is given on a label near the termination of the cable.

Operating Temperature Range: 0°C to +50°C

Conductivity Range: Approx. 0.005 to 7.5mScm-1

Accuracy:* In KCl and Na

2SO4, NaHCO3, and NaCl standards at 25°C

±5% of reading, 0.45 to 7.0mScm-1

±10% of reading, 0.005 to 0.44mScm-1

* User calibration of individual probes may improve the quoted accuracy.

Temperature Sensor

Thermistor: Betatherm 100K6A1

Range: 0°C to +50°C

Accuracy:

±0.4°C (worst case)

A547 Interface:

Size: 63.5 x 22.2 x 44.5mm

Weight: 170g

Temperature Range: -15°C to +50°C

Multiple sensors can be measured by connecting the

probes to an AM16/32B multiplexer and then connecting the

multiplexer to a single A547 interface
