2.5 ESD Protection Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits. Vaisala products are adequately protected against ESD for their intended use. However, it is possible to damage the product by delivering an electrostatic discharge when touching, removing or inserting any objects inside the equipment housing. -
Page 12: Hmp7 Probe
[in] Figure 5 HMP7 Probe Head Dimensions Vaisala HUMICAPâ Humidity and Temperature Probe HMP7 is designed for applications that involve constant high humidity or rapid changes in humidity such as drying and test chambers, combustion air and other humidifiers and meteorological measurements where measurement performance and chemical tolerance are essential. -
Page 13: Hmp8 Probe
Chapter 2 – Product Overview • Stainless steel mesh filter standard in delivery Probe Heating HMP7 supports probe heating. Probe heating heats up not only the sensor, but the entire probe head. When probe temperature is heated above dew point temperature, condensation on the probe can be avoided while measuring the dew point temperature of the process. -

When adjustment is necessary, you can have Vaisala calibrate and adjust the probe. To order calibration services from Vaisala, visit store.vaisala.com. You can also do the adjustment yourself using the Insight software. -
Page 26: Adjustment Points And Requirements
Insight software and repeat the adjustment procedure. Make sure the measurement has stabilized and the reference environment is reliable. If the required adjustment is still too large, the probe needs to be serviced by Vaisala. When adjustment of humidity measurement is necessary, Vaisala recommends adjusting in two points, 11 %RH and 75 %RH. - Page 27 Chapter 6 – Maintenance 4. Select the type of adjustment to perform: RH adjustment or T adjustment. 5. Define the needed adjustment for the first measurement point: a. Insert the probe head in the reference environment for the first calibration point. b.
