Operating Range:
10°C above ambient to 150°C
Temperature Uniformity:
+/- 0.5°C
Temperature Stability:
+/- 0.5°C
Ambient Operating Range:
17-27°C
Relative Humidity Operating Range:
20-80%
Note:
The thermal values are based on temperatures read from a thermometer inserted into the thermometer well of the
Reacti-Block™ Aluminum Block. The thermal values may vary slightly as a result of variable load and aluminum block
size. Block weight will vary with the size and number of holes drilled into each block.
Warning:
The Reacti-Therm™ Heating Module is not explosion-proof. It is primarily designed for aqueous systems.
Do not use this module in the presence of flammable gases or liquids, ignitable dust or mist-forming materials.
Environmental Conditions
Operating
15°C to 30°C; 10% to 85% relative humidity at 25°C, noncondensing. Installation Category II (over-voltage) in accordance
with IEC 664. Pollution Degree 2 in accordance with IEC 664. Altitude limit: 2,000 meters
Storage
-25°C to 65°C; 10% to 85% relative humidity
Set-up
Before You Begin:
Examine carton and Reacti-Therm™ Heating Module for damage before use. Call the delivery carrier
and immediately file a claim if shipping damage is observed. Do not discard packaging material.
Inspect the condition of the unit before use. Place the instrument in an area free of drafts and heating devices for the most
uniform temperature control of samples. Inefficient or uneven heating may result if the Reacti-Therm™ Heating Module is
placed in a fume hood with a high blower speed. Place a clean Reacti-Block™ Aluminum Block into the well. Place a 35 mm
immersion depth thermometer with a range above 165°C into the thermometer well of the aluminum block.
Start Up:
With the power switch in the "off" position, plug the three-prong plug of the power cord into a 120 volt outlet. Flip
the power switch to the "on" position. Turn the temperature control knob clockwise to raise the temperature;
counterclockwise to lower the temperature. Adjust the temperature control knob so that the thermometer temperature in the
block will read 100°C when equilibrated. The heat indicator light comes on when the instrument is heating, and the light
flickers as the temperature approaches 100°C. Allow 30 minutes for the temperature to stabilize after the indicator light
begins flickering. This procedure allows you to verify that your Reacti-Therm™ Heating Module is heating properly.
Instructions for Use
1. Place the Reacti-Therm™ Heating Module in a thermally stable environment. Avoid locating the instrument near air
vents or heating equipment.
2. Place a Reacti-Block™ Aluminum Block into the heating well of the Reacti-Therm™ Heating Module. The well and the
block should be free of debris and contamination to facilitate even and efficient heating.
3. With the power switch in the "off" position, plug the three-prong plug into a 120 volt outlet.
4. Flip the power switch to the "on" position and turn the temperature control knob clockwise to raise the temperature;
counterclockwise to lower it.
