Water or air, measure H2S where it matters – right at the source.
Meet the new GS1440 and GS1440EX hydrogen sulfide sensors from Hach. Whether in water or air, you will have the direct H2S measurement you need to optimize your H2S treatment process and proactively control H2S before it causes issues.
–5 to 70 °C (23 to 158 °F) pHD and ORPBefore initial pH calibration, calibrate the temperature measurement when the sensor is in water or buffer which is at approximately the same temperature as the pH buffers.
-5 - 70 °C (23 - 158 °F) pHD and ORPBefore initial pH calibration, calibrate the temperature measurement when the sensor is in water or buffer which is at approximately the same temperature as the pH buffers.Please Note:When the sensor is placed into the application sample, if that sample is more than 10-°C (18-°F) different than the previous temperature/pH calibration, then it is recommended to recalibrate the temperature while the sensor is in the sample to maintain the ±0.5-°C (±0.9-°F) temperature accuracy specification.
