What Separates the Hanna HI98190 From a Pocket Pen
Bench accuracy in a case you can carry. It resolves 0.001 pH and reads to ±0.002, against the ±0.1 a pocket tester manages. The electrode is titanium bodied, chemically resistant and effectively unbreakable, on a quick connect DIN that seals without any threads.
Trusting a Portable ORP Meter Out in the Field
Accuracy you cannot verify is not accuracy. A portable orp meter lives in a bag, gets knocked about and drifts, which is why CAL Check is the feature that earns its keep. It compares the current calibration against the last one and tells you whether the probe needs cleaning, is broken, or the buffer has gone off. After calibrating, probe condition shows as a percentage from 0 to 100. Calibration runs up to five points across seven standard buffers and five custom ones. AutoHold freezes a stable reading so you can write it down, and log-on-demand stores 200 samples, 100 pH and 100 mV. It is IP67 and runs about 200 hours on four AA cells.
Key Features
- 0.001 pH resolution, ±0.002: Bench figures in a field body, where a pocket pen gives you ±0.1.
- Titanium body electrode: HI12963, chemically resistant and near unbreakable, on a threadless DIN.
- CAL Check: It tells you whether the probe is dirty, broken, or the buffer has gone off.
- Five point calibration: Seven standard buffers plus five custom, with slope shown from 80 to 110%.
- 200 sample log on demand: 100 pH and 100 mV, moved over micro USB with HI92000 software.
- IP67 and about 200 hours: Four AA cells, in a thermoformed hard case with buffers and beakers.
