Gemini 550 Dryblock Temperature Calibrator. Temperature range 35ºC to 550ºC
Gemini 700 Dryblock Temperature Calibrator. Temperature range 50ºC to 700ºC
High Capacity Dry Block Calibrators.
The Gemini Dryblock range differs from our other dry blocks with an enormous well capacity of more than 2.5” While still offering all the advantages you’ll find in other calibrators the Gemini has been designed to have a large block suitable for more probes.

The Gemini Dryblock calibrators are available in two models, the BASIC (B) and the SITE (S).
The B model includes a sophisticated temperature controller with a dual display for Set Temperature and Dry Block Temperature. The large block has the benefit of higher capacity but with longer heating and cooling times compared to the fast response models.

• Calibrate Whole Calibration Loop.
  Using a heat source rather
  than an electrical simulator a test
  instrument and probe can be calibrated
  as a system.

• High Capacity Block -- Large Calibration 
  volume for many sensors and low loading
  errors.

• Two Operating Ranges -- Fast response
  from 35ºC to 550ºC (1022°F) or
  50ºC to 700ºC (1292°F)

• Simple To Use -- Outstanding Value for Money!

Includes as standard: 
Windows Software, Computer Interface and a Ramp to Set Point Feature.
Increased resolution of ±0.01 available throughout the range via the PC interface and 
from 0.01to +99.99 locally on the auto-ranging front display. 
The controller features multi-point block to display correction giving excellent absolute accuracy.
The SITE model has universal sensor input allowing Platinum Resistance Thermometers, Thermocouples (Types K, N, R, S, L, B, PL2, T, J and E) along with Linear Process Inputs including 4-20mA current transmitters to be displayed on the built-in indicator. 
The indicator can be programmed with up to five calibration points to provide high accuracy digital probe matching.
The indicator and controller are both addressable over the communications link.
