Hach-Lange H-Series Meters Basic User Manual - Manual (Page 7)

Product overview
N O T I C E
Always disconnect power to the meter when electrodes are changed. Only use the meter as instructed in this
manual or the meter performance can decrease.
The H-series handheld and benchtop meters operate with glass sensor electrodes with BNC
connectors or non-glass probes with ISFET (ion sensitive field effect transistor) silicon chip sensors.
The meters use one pH electrode (a BNC pH electrode or an ISFET pH probe) at a time. When the
meter power is set to on, the meter automatically identifies the type of electrode that is attached.
The H-Series meters are available in eight models:
• Waterproof handheld meters with Bluetooth ™ technology. Refer to Figure 1 :
• H160G—pH and ORP
• H170G—pH, ORP, conductivity, TDS and salinity
• Benchtop meters with a USB output. Refer to Figure 2 :
• H260G—pH and ORP
• H270G—pH, ORP, conductivity, TDS and salinity
• H280G—pH, ORP, conductivity, TDS, salinity and dissolved oxygen (DO)
• Benchtop meters with Bluetooth ™ technology and a USB output. Refer to Figure 2 :
• H260GB—pH and ORP
• H270GB—pH, ORP, conductivity, TDS and salinity
• H280GB—pH, ORP, conductivity, TDS, salinity and DO
Note: The difference between the benchtop meters is that the GB benchtop meters have Bluetooth ™ technology
and a USB output, and the G benchtop meters only have a USB output. Unless noted, when the benchtop series is
documented in this manual, the benchtop meter includes all of the H-series benchtop meters (both the G and the
GB benchtop meters).
