HI8424 ORP /°C Meter

Product information "HI8424 ORP /°C Meter"

HI 8424-ORP is one of the most popular ORP meters on the market. This instrument has been configured to perform ORP and temperature measurements with a high degree of accuracy and fast response.

It is supplied with ORP probe HI3230B and can be verified with ORP Test solution (HI7021 or HI7022).

Future upgrade can be done for pH measurement by exchanging the ORP probe with the pH Probe (recommended HI1230B for general purpose usage).

Order Information : HI 8424 is supplied with HI 3230B ORP electrode, HI 7662 temperature probe, HI 700661 electrode cleaning solution sachets (2), battery, protective case and instructions.
