Rotronic HP22 Humidity Temperature Handheld Indicator

DISCONTINUED ITEM-Recommended Replacement: Rotronic HP32 HygroPalm Humidity Temperature Handheld Indicator

The HP22 is a versatile hand-held indicator that displays relative humidity, temperature and a calculated parameter such as the dew or frost point, based on the measurements of a HygroClip 2 plug-in probe.

Selecting the appropriate probe model from the HP22 probe options is done based on the application. Depending on the probe model, the measuring range is within 0 to 100 %RH and -100°C to 200°C (-148°F to 392°F). The HygroClip 2 probes feature durable sensors and consistent performance. All HygroClip 2 probes can be hot-swapped to facilitate routine calibrations.

The HP22 indicator has an extensive set of settings and functions that can be configured and enabled by the user with the ROTRONIC HW4 software. In spite of its sophistication, the HP22 can still be used just as a simple humidity and temperature indicator. Whether you decide or not to take advantage of its full potential, the HP22 will let you have it your way.

Note: Probe Sold Separately

• Measures relative humidity and temperature
• Calculates dew point, frost point, wet-bulb temperature, mixing ratio, etc.
• Interchangeable HygroClip 2 probe (sold separately) – can be separated from the HP22 by up to 5 m / 16.4 ft.
• Operating limits at probe 0 to 100 %RH and -100 to 200 °C (-148 to 392 °F) – depending on probe model
• Accuracy at 23 °C: ± 0.8 %RH and 0.1 °C
• Temperature unit (°C or °F) selectable from the keypad
• Uses a regular 9V alkaline battery
• LC display with backlight – shows %RH and temperature or %RH, temperature and calculated parameter (keypad selection)
• Data recording (%RH and temperature) – up to 2000 value pairs
• Automatic RH sensor drift test with optional correction
• 1-point or multi-point humidity adjustment of the probe directly from the keypad
• 1-point temperature adjustment of the probe directly from the keypad
• External service connector for full access to the settings and functions of both the HP22 and probe

The HygroPalm2-series (with integrated or interchangeable probes) is ideal for all applications where exact measurement of humidity and temperature is of decisive importance, e.g. the food and pharmaceutical industries, printing and paper industries, many trades, the sciences, meteorology, agricultural sector, climatology, etc. There is hardly a field today in which these parameters may be ignored. It is ultimately the measuring task at hand that defines the HygroPalm instrument that best meets your needs.
