Using and Caring For Your ThruMomete

Maintaining your ThruMometer

Proper maintenance of your new ThruMometer in-line thermometer will yield you years of trouble-free use and accurate readings.

Sanitize your ThruMometer before use using a non-caustic cleanser such as iodophor Do not immerse for longer than necessary to extend the life of the films. Do not use bleach.

Clean with mild detergent only, using warm, but not hot water. In no case exceed 140oF as this will permanently damage the liquid crystal temperature elements and cause the thermometer to lose accuracy.Do not soak in same bucket with other metals to prevent galvanic corrosion to the aluminum.

Aggressive cleansers, especially bleach, will not only erode the aluminum over time, it will cause delamination of the clear protective film covering the liquid crystal thermometer.Delamination of the films from use of improper cleansing agents are not covered under warranty.After use, dry thoroughly and store in the protective plastic tube.

Using your ThruMometer

The highly conductive aluminum body and liquid crystal thermometer are VERY fast responding (up to 1oF/sec), very accurate (0.5oF) and allow you to dial in your desired temperature easily to within 1oF.

Connect the ThruMometerâ„¢ to the "wort out" side of your heat exchanger using 3/8" ID hose and another hose directly into your fermenter. The non-serrated fittings on the thermometer are designed for a snug "press-fit" on the hose .As such, hose clamps are not necessary if you drain the outlet hose of the thermometer directly into the fermenter.If you have downstream restriction you should use clamps on the end fittings to prevent leaks or a hose blow-off.

Use: before pumping hot wort through your heat exchanger, turn the cooling water on to the maximum flow rate.This will prevent "overheating" the liquid crystal thermometer elements.In all cases, do not exceed 140oF. Slowly increase the hot wort flow rate until you reach the desired temperature.If you never see a change in color on the thermometer, carefully touch the side of the ThruMometer and determine if the temperature is above 88oF or below 58oF.If above 88oF, slow down the beer flow rate.If below 58oF, increase the wort flow rate.If it is still too cold, slow down the water flow rate.

Note: most heat exchangers do not work well at very slow flow rates.At low flow rates the flow is non-turbulent and does not give up or take on heat readily.If you are at a very slow wort flow rate and at maximum water flow, you may be experiencing this "laminar flow" phenomenon in your exchanger.Increasing the wort flow rate will generate turbulence and greatly increase the performance of the heat exchanger.Heat exchangers such as the Therminator have a chevron pattern stamped into the plates and therefore create turbulence even at very low flow rates.Chillers made from smooth walled coiled copper tube do not generate turbulence as easily.
