This document introduces a pH and temperature measuring instrument with features such as waterproof microprocessor treatment, large LED display, and rubber protection ring. The instrument has automatic or manual temperature compensation, easy calibration method, low power indication, etc. The measurement range is 0.00 to 14.00 pH and 0 to 100℃, with an accuracy of 0.02 pH, 2mV, and 0.5℃, and a resolution of 0.01 pH, 1mV, and 0.1℃.
The MP-101/103 is a handheld pH/ORP meter with a waterproof housing, large LED display, and both automatic and manual temperature compensation. It runs on a DC 9 V battery and features auto power‑off after 10 minutes of inactivity.
The manual covers preparation steps, calibration using pH 4.00 and 7.00 solutions, switching between pH and ORP modes, and measurement procedures. It also lists dimensions, power‑indicator behavior, and basic operating instructions. This manual is written in Chinese.
| Automatic temperature compensation range | up to 100 °C (MP-103) |
|---|---|
| Manual temperature compensation range | up to 100 °C (MP-101) |
| Calibration points | pH 4.00 and 7.00 |
| Power supply | DC 9 V |
| Dimensions | 108 × 75 × 30 mm |
| Auto power‑off after inactivity | 10 minutes |

Hold the CAL key for 3 seconds to enter calibration mode, then immerse the electrode in pH 4.00 solution until the display shows 7.00, and repeat the step with pH 7.00 solution.
It operates on a DC 9 V battery.
The meter measures pH from 0 to 14.00.
