ADWA AD110 Portable pH Meter

Measure pH with Automatic Temperature Compensation

The ADWA AD110 Portable pH Meter combines pH and temperature measurement in a compact instrument designed for laboratory, water quality, agriculture and field testing. It provides a wide -2.00 to 16.00 pH measurement range with 0.01 pH resolution and ±0.02 pH accuracy.

The AD110 is supplied with a separate epoxy-body pH electrode and stainless-steel temperature probe, allowing temperature to be measured alongside pH and used for automatic temperature compensation.

Wide -2.00 to 16.00 pH Measurement Range

The AD110 measures across a wide pH range from -2.00 to 16.00 pH with 0.01 pH resolution, making it suitable for a broad range of aqueous sample testing applications.

±0.02 pH Accuracy

With a specified pH accuracy of ±0.02 pH at 25°C, the AD110 is designed for applications requiring more controlled measurement than a basic pocket pH tester.

Automatic 1 or 2-Point Calibration

Calibration can be performed automatically at one or two points. The meter incorporates three memorised buffer values at pH 4.01, 7.01 and 10.01, with automatic buffer recognition simplifying routine calibration.

Automatic Temperature Compensation

When the supplied temperature probe is connected, the AD110 provides Automatic Temperature Compensation (ATC) to compensate pH measurements according to the measured sample temperature.

Temperature compensation can also be operated at a fixed 25°C when automatic temperature measurement is not required.

Separate Stainless-Steel Temperature Probe

Unlike meters relying on a temperature sensor integrated into the pH electrode, the AD110 is supplied with a separate AD7662 stainless-steel temperature probe with a 1 metre cable. Temperature can be measured from -5.0°C to +105.0°C.

Replaceable Epoxy-Body pH Electrode

The supplied AD1230B pH electrode features an epoxy body, BNC connector and 1 metre cable. The replaceable electrode design allows the measuring electrode to be changed when required without replacing the complete instrument.

Hold Function for Easier Reading

The HOLD function allows the displayed measurement to be retained for convenient viewing and recording after a measurement has been taken.

Long Battery Operating Life

Four AA alkaline batteries provide approximately 1,500 hours of operation under the manufacturer’s specified conditions. Automatic power-off after eight minutes of inactivity helps conserve battery life.

Designed for Laboratory and Field Measurement

The portable design makes the AD110 suitable for routine pH testing in laboratories as well as measurements carried out around water treatment facilities, agriculture, aquaculture and environmental monitoring applications.
