AD110 pH/temp meter

ADWA AD110: a professional portable pH and temperature meter with an external electrode

The AD110 pH/temp meter is a portable meter for field and laboratory measurement of pH and sample temperature. A large LCD shows the selected parameter, and automatic temperature compensation adjusts the pH measurement to the sample temperature. It is suitable for laboratories, water analysis (aquariums, pools, treatment plants), the food industry, brewing and agricultural soil analysis.

The set includes an AD1131B glass pH electrode with a 1 m cable and BNC connector, an AD7662 stainless steel temperature probe with a 1 m cable, pH 4.01 and 7.01 calibration solutions (20 mL each), four AA batteries and a manual.

According to the official ADWA manufacturer's instructions it measures pH in the range from −2.00 to 16.00 with a resolution of 0.01 pH, and temperature from −5.0 to 105.0 °C.

How it works and how to calibrate it

Dip the electrode and temperature probe into the sample, stir gently and wait for the value to settle. The SET/HOLD key freezes the display and selects the measuring range. Rinse the electrode between samples so that the samples do not mix.

Calibration is automatic: the meter recognises the 4.01, 7.01 or 10.01 buffer by itself. Two-point calibration is recommended. Dip the electrode and probe into the 7.01 buffer, press CAL and confirm with SET/HOLD when the value stops flashing. Then dip them into the 4.01 or 10.01 buffer and confirm again. The meter returns to normal mode. If the buffer value is wrong, the message Ec appears.

Who is it for

Choose it when you need a meter with an external electrode and temperature probe, for example for water, soil and fertiliser analysis or for control in food production. If you also need ORP, see the AD111, and for a waterproof version the AD131 or AD132. For simple pocket measuring there is the AD-12 pH meter.

Maintenance: AD110 pH/temp meter

Storing and cleaning the electrode

Keep the electrode in its protective bottle so that the glass bulb stays moist. Top up with storage solution if needed. Check the cable and electrode regularly: if you notice cracks or damaged insulation, replace the electrode, and keep the connectors clean and dry. Clean the electrode with a pH electrode cleaning solution and then recalibrate the meter. The replacement temperature probe is the AD7662.
