Glass Body
The glass body of the HI1414D/50 is chemically resistant and quick to reach thermal equilibrium, allowing for a faster, more stable response
Flat Tip
The flat tip sensing bulb allows for the direct surface measurement of skin. Maximum surface contact is achieved with this specialized tip shape.
Open Junction Reference
The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable reading
Built-in Temperature Sensor
Errors in calibration and measurement are eliminated with the Automatic Temperature Compensation provided by the integrated temperature sensor.
