Features

top

Large Display Screen — Large dual-display LCD for enhanced readability. Important meter functions such as mode, ATC, battery level and temperature (pH 30 only) are clearly displayed for your convenience, at all times.

Temperature Display — pH 30 displays both the pH and temperature values, simultaneously, pH is displayed on the top of the screen, while temperature is on the secondary display. You can choose to read temperature in °C or °F.

Calibration Buffer Sets — Choose either the USA (pH 4.01, pH 7.00 and pH 10.01) or NIST (pH 4.01, pH 6.86 and pH 9.18) buffer sets.

Push-Button Calibration With Buffer Recognition — Calibration is quick and easy with simple two-button operation. In the calibration mode, your pocket tester auto-detects and displays buffer value in the lower display, minimizing calibration errors. Three-point calibration ensures accuracy across the entire pH scale.

User-Replaceable Double-Junction Sensor — Replace the sensor yourself! No tools or messy soldering is necessary. Sensors are equipped with a double-junction construction minimizing reference element poisoning. Replacement sensor is sold separately.

Non-Volatile Memory — Your calibration data is safe when you power off or change the batteries. EEPROM retains all the vital information.

Auto-Power Off — Meter automatically powers off after 8.5 minutes of non use to conserve battery life and save you money.

Hold Function — Freeze measured values for later reading and recording, especially useful when you are in dimly lit or confined areas.

Self-Diagnostic Messages

Battery Battery power level indicator
Or/Ur Over or under-range, for pH and temperature (pH 30) values
ATC/Or/Ur When blinking, problem associated with the temperature sensor
Er.0 Temperature calibration error
Er.1 pH calibration error

Warranty — Free from manufacturing defects for 1 year and electrodes for 6 months.
