AD331 is a waterproof portable meter that reads Conductivity in 5 ranges and temperature. The autoranging feature of the EC range automatically sets the instrument to the scale with the highest resolution.

Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). It is also possible to disable the temperature compensation feature to measure the actual conductivity.

The temperature coefficient is user selectable. This instrument also features a measurement stability indicator, GLP capability, and a user selectable ID code to uniquely identify the instrument.

AD330 and AD332 are waterproof portable meters that read TDS and Conductivity in 5 ranges and temperature.

The autoranging feature of the EC and TDS ranges automatically sets the instrument to the scale with the highest resolution. Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). It is also possible to disable the temperature compensation feature to measure the actual conductivity.

The temperature coefficient is user selectable. These instruments also features a measurement stability indicator, GLP capability, and a user selectable ID code to uniquely identify the instrument.

Moreover, AD332 includes PC interface and printing function. Connect the meter to an external serial printer with the following printer specifications:

• at least 16 characters / line

• baud rate 9600

• 9-pin RS232 input

AD310 and AD410 are portable microprocessor-based instruments for measuring EC or TDS, and temperature.

The autoranging feature of the EC and TDS readings automatically sets the instrument to the scale with the highest resolution. Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). The temperature compensation feature can also be disabled to measure actual conductivity or TDS.

The temperature coefficient is user selectable. The instuments also feature a measurement stability indicator.

Both models are supplied complete with A76309 conductivity probe with built-in temperature sensor and 1 m cable, batteries (4 x 1.5V AA alkaline) and instruction manual.

AD310 is supplied complete with A76309 conductivity probe with built-in temperature sensor and 1 m cable, calibration solution at 1413 μS/cm (20 ml sachet ), 1.5V AA alkaline batteries (4 pcs) and user manual. AD410 is supplied complete with A76309 conductivity probe with built-in temperature  sensor and 1 m cable, calibration solution at 1382 ppm (20 ml sachet), 1.5V AA  alkaline batteries (4 pcs) and user manual.

AD31 and AD32 are waterproof Conductivity, TDS and temperature testers. The housing has been completely sealed against humidity. All Conductivity and TDS readings are automatically temperature compensated (ATC), and temperature values can be displayed in °C or °F units. The Conductivity/TDS conversion factor (CONV) can be selected at one point. Measurements are highly accurated with a unique stability indicator right on the LCD. The models are also provided with a low battery symbol which warms the user when the batteries need to be replaced. The AD32P probe supplied with the meters, is interchangeable and can be easily replaced by the user. The encapsulated temperature sensor allows fast and accurate temperature measurements and compensation.

The testers are supplied in a box complete with protective cap, 4 x 1.5V batteries and user manual.

AD33, AD34, AD35 and AD36 are waterproof Conductivity and TDS testers, that also measure temperature. The housing has been completely sealed against humidity. All Conductivity and TDS readings are automatically temperature compensated, and  temperature values can be displayed in °C or °F units. Conductivity (or TDS) calibration is automatic at onepoint, while temperature range is factory calibrated and can only be adjusted by the user. The AD33P probe supplied with the meters, is interchangeable and can be easily replaced by the user. The encapsulated temperature sensor allows fast and accurate temperature measurements and compensation. To prolong battery life, these models are provided with an auto-off feature that turns them off after 5 minutes of non-use. Moreover, when batteries become too weak to ensure reliable readings the meter automatically turns off.
