400563 1912 Wireless Upgrade Kit D (RH) 635/435 (USA / Canada) by Testo

Kits includes:

• 0636 9736 - RH probe head (435/635) 2%
• 0554 0191 - Wireless handle TC with t/c adapter
• 0554 0190 - Wireless module

400563 6251 625 Hygrometer Remote Probe Kit by Testo

The compact instrument with built-in humidity probe head for measuring air moisture and temperature. The large 2 line display shows humidity, wet bulb temperature or dewpoint as well as temperature. When measuring at hard-to-access points, the humidity probe head can be easily removed and attached to the handle via the probe cable (accessory). Alternatively, the readings can be transmitted wirelessly over wide distances from the probe to the measuring instrument. To do this, the humidity probe head is attached to the radio handle (accessory) and the radio module (accessory) is added to testo 625.

Kit Includes:

• 0563 6251 - 625 Hygrometer with integral humidity probe head
• 0516 0201 - Compact class service case
• 0430 9725 - Handle for RH probe head 625, includes cable

• Displays temperature and relative humidity / wet bulb temperature / dewpoint
• Max./min. values
• Hold button to freeze readings
• Display light
• Auto Off function
• TopSafe, the indestructible protection case (optional)
• Patented humidity sensor
• 2 year guaranteed long-term stability
• TopSafe, instrument protection against dirt and knocks (optional)

400563 6352 635-2 Compact Pro Dewpoint (HPD) Kit by Testo

The instrument for measuring air moisture, material equilibrium moisture and pressure dewpoint in compressed air systems. Moisture characteristics can be recorded in the instrument memory and analysed and displayed in graphics or tables. Up to 3 temperature or humidity probes can be displayed in the testo 635-2 meter; data transmission is by radio i.e. wireless. Selectable user profiles, i.e. allocation of specific function buttons and menu-guide to an application enable intuitive operation. Material moisture can be displayed immediately on account of the special probe. Characteristics for different materials can be stored in ComSoft and transmitted to the instrument. testo 635 immediately displays the dewpoint difference between ambient air and the wall surface in the analysis of moisture on walls and ceilings. Precision probes up to -60°C tpd are available to check pressure dewpoint in compressed air systems. The humdity sensor developed by Testo has proven itself worldwide and has outstanding features in terms of precision, long-term stability, temperature resistance and robustness.

Kit Includes:

• 0563 6352 - 635-2 with memory & software
• 0636 9836 - Precision Press Dewpoint Probe
• 0516 0435 - Deluxe service case for Compact Pro

• Instrument memory for up to 10,000 readings
• PC software for analysis, filing and documentation of measurement data
• Measurement of air moisture, material equilibrium moisture, pressure dew point
• Radio probe for temperature and humidity
• Protection class IP54
• Direct display of material moisture due to freely settable characteristics curves (based on equilibrium humidity)
• Storage of single measurements or measurement series by measurement location
• Fast access to the most important functions via user profiles
• U-value probe connection option
