Retort and pipe thermometers


The retort thermometer was developed in co-operation with leading canning companies to match the particular requirements of the industry to both safeguard public health and to produce canned foods of the highest quality. 
As well as instruments manufactured under the Russell Scientific Instruments' name, we manufacture, service and repair Tetcol retort thermometers, Short & Mason, Tycos, Taylor and other makes. 
Thermometers can be supplied straight or angled and with or without a clear plastic window. A works certificate is supplied for guaranteed accuracy of performance. The retort thermometer incorporates many safety features including: 
A sealing gland to eliminate any movement of the thermometer against the scale while working under steam pressure 
A check datum line
Easy reading reflecting glass to magnify the mercury column 
Approximately 210mm length scale with wide divisions for greater accuracy 
Heavy, robust brass protective cases with stainless steel immersion

Construction features: 
The scales are very clear and easy to read. The datum line is used to show that the tube has not moved. The frame and scales are all numbered for record keeping purposes. Installation of the thermometer is very easy as the swivel nut turns freely on the stem. A retort thermometer can be installed very quickly in a separable well. The separable well connection is installed permanently in the apparatus as this gives it the best resistance to prevent contamination, and eliminates any need to draw-down the plant. 

Pipe thermometers
Pipe thermometers are a budget instrument for checking the temperatures of liquids flowing through pipes. They are available in two forms: straight or right angle.
Immersions, connection details and temperature range are all available on application to match your design and specific requirements.
