7. Press CAL key to set temperature value. Press ENTER key to confirm; the display shows “YES/HOLD” indicating that the auto-hold function is enabled. Enter If the auto-hold function is enabled, the unit will automatically sense a stable endpoint reading and freeze the reading in the display. If you disable this function, the unit allows user to freeze the reading in the display manually by pressing the HOLD key. -
Page 7: Single Point Calibration
pH Calibration: The HL101 pocket pH/temperature tester allows up to 3 point calibration. We recommend that you perform at least a 2 point calibration for best accuracy. The unit automatically recognises and calibrates to the following standard buffer values. ● USA Standard Buffer Options: pH 4.01, 7.00, 10.01 ●... - Page 8 Rinse the pH electrode with distilled water. Immerse the electrode in the pH 4.01 buffer solution. Stir the solution gently. Press ENTER key to confirm. Wait for the measured value to stabilize; the display shows electrode slope and “END”. 2 point calibration is completed. Enter 3 POINT CALIBRATION (not required for normal operation): Ensure that 3 point calibration is selected in the setup menu.

Questions and answers
How does it operate
The Trace2O HydroLite HL101 operates as a pH and temperature meter with an LCD display that shows measured values, units, and mode indicators. It has three modes: MEAS (measurement), CAL (calibration), and SETUP. The unit features automatic temperature compensation (ATC) and a HOLD function to freeze readings.
To use it, remove the electrode cap and, if needed, soak the electrode in 3M KCL solution or tap water for at least 15 minutes. Do not use distilled or deionized water. Turn the device on by pressing the ON/OFF key. To turn it off, hold the ON/OFF key for 5 seconds or allow it to auto-off after 8 minutes of inactivity. The auto-off function can be disabled in the setup menu.
The device supports 1 to 3-point calibration using USA (pH 4.01/7.00/10.01) or NIST (pH 4.01/6.86/9.18) standards. It measures pH in the range of -1.00 to 15.00 with an accuracy of ±0.01 pH and temperature from 0 to 60°C with an accuracy of ±1°C. It operates on two AAA batteries.
