The Master Series pen meters are pocket-sized, Bluetooth testers for pH, ORP, conductivity or pH and conductivity together. They send readings in real time to an app on your phone or tablet, where you can tag samples, set alarms and store timed readings. The pH meter reads −2.00 to 16.00 pH to ±0.01 pH, with automatic 1 – 3 point calibration and temperature compensation from 0 to 60 °C. Each kit comes in a hard carrying case with its calibration solutions, sample vials and batteries. They suit water testing, fieldwork, food and beverage QA, aquaculture and agriculture.
Why buyers choose the Master pen meters

Where it is used
Water quality testing, environmental fieldwork, food and beverage QA, aquaculture, agriculture, and labs that need a quick check at the bench.
Questions buyers ask
P200PEN for pH, ORP200PEN for ORP, C200PEN for conductivity, TDS and salinity, or PC200PEN for pH and conductivity in one pen.
Readings go straight to the app on your phone or tablet, where you can label samples, set alarms and store readings at set intervals.
pH calibrates automatically at 1 to 3 points with the buffers supplied, and the meter reminds you when calibration is due.
Four 1.5 V AAA alkaline batteries, fitted in the kit.
