Specialty Meters

Hach® Dual-Technology ISFET Non-Glass pH Benchtop Meters

Use ISFET or standard glass electrodes – Good Laboratory Practices (GLP) compliant with time-date stamp data logging, password security, and recalibration alarm

– Graph and collect data on your PC

– Expanded pH range

– Ion concentration measurement capability

Versatile benchtop meters offer dual-technology pH measurement with the convenience of ISFET compatibility for low maintenance, while still allowing the flexibility of using inexpensive glass or epoxy pH electrodes. Stainless steel ISFET probes are stored dry and require no maintenance. These GLP-compliant meters feature 999 data point memory with time-date stamping, PC data manipulation software, calibration recall and alarm, and password protected setup.

Meters include: data graphing and logging software, AC power supply, and four AA batteries.

pH meter with probe adds: ISFET pH probe (59540-46).

pH/conductivity meter with probe adds: conductivity probe (99360-29).

Multiparameter meter with probe adds: dissolved oxygen probe (59545-70).
