FEATURES
  • Large display screen
  • Up to ±0.01pH accuracy
  • Microprocessor based
  • Three-point (USA or NIST) push-button calibration with buffer recognition
  • User-replaceable double-junction, polymer sensor
  • Simultaneous temperature display in °C or °F (pHTestrs® 30 only)
  • Automatic Temperature Compensation (ATC)
  • Self-diagnostic messages
  • Non-volatile memory
  • Freeze and Auto-off functions

 

 

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 i 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, below right.

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 nonuse 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 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.
