Rotronic Humidity and Temperature Calibration Ampoules | EAXX-SCS
Price range: R1,801.00 through R6,130.00 ex vat
Rotronic Humidity and Temperature Calibration Ampoules - Overview

Being equipped with the correct devices and software makes calibrating and adjusting probes on-site at your premises easy. Rotronic calibration devices are small, airtight chambers that fit any 5/12/15/25 mm probes (Rotronic standard 15/25mm). The lower part of the device consists of a screw-on lid. The humidity standard is poured onto an absorbent textile pad into the screw-on lid. The specified humidity is generated in the calibration device after a stabilisation period. High humidity values require a longer stabilisation period. The probe can then be calibrated or adjusted by comparison with the reference value of the humidity standard.

Rotronic Humidity and Temperature Calibration Ampoules - Features
- Simple and safe use
- Traceable to national standard
- Inexpensive calibration on-site
- Unlimited lifetime as long as the glass ampoules are kept sealed

Whirling Hygrometer with Case | T102
R550.00 ex vat
Whirling Hygrometer with Case - Overview

The Whirling Hygrometer, also known as a Sling Psychrometer, is used for measuring relative humidity. It is made from two thermometers mounted on a frame which rotates around a handle and is whirled in the air by hand. One thermometer is covered with a tight-fitting muslin sock which is kept wet by (preferably) distilled water. This type of thermometer is known as the wet-bulb thermometer. The other is the dry-bulb thermometer and exposed to the atmosphere directly. Where the air is less than 100 per cent relative humidity, the wet bulb will display a lower temperature than the dry bulb known as wet-bulb depression. A special chart is used to convert the wet-bulb depression to relative humidity, or the relative humidity can be determined by correlating the readings with those on a simple slide rule, which is supplied with each instrument.

Whirling Hygrometer with Case - Features
- Carry case
- Slide rule
- No mercury
