Introduction
to Temperature Testers
Isotech Dry Blocks have the features and performance to meet most
calibration needs. Sometimes there are applications where a compromise
has to be made, with regard to size or price. An engineer forced to
carry a calibrator up a ladder and into a confined space might have
to sacrifice performance for physical size. Where sensors of small
dimensions and large uncertainties are used. Isotech have developed
a range of products called “Testers”.
They
don't have the same immersion depths that larger baths have, the blocks
are smaller and the dry blocks do not have a PC interface.
What
they do have is:
- Outstanding
Value
- Compact
Size - true handheld models
- Wide
Operating Ranges, from less than -10ºC to 650ºC in three
models
- Fast
Response
QuickCals
 There
are two QuickCal models, handheld, portable and capable of operating
from below -10ºC to 350ºC.
