Lab Expo offers Benchtop pH Meter 25-BPM103 designed to measure -2.000 to 20.000 pH range and is suitable for daily pH measurement, and testing. 1 to 5 points push-button calibration is performed using standard USA or NIST pH buffers & 1 point calibration to measure ORP. It offers automatic or manual temperature compensation mode for pH measurements. The pH meter with a sleek design has an easy-to-read backlit LCD screen that shows pH measurements & temperature simultaneously.
