Wet bulb Thermometer - checking humidity directly
Comparing wet and dry bulb thermometers is the most accurate, low cost method for measuring Relative Humidity. Simple, direct reading hygrometers are available but vary widely in accuracy and are not recommended. The Brinsea wet bulb thermometer is specifically designed for use with the Octagon 20 and 40 and comes with conversion chart showing Relative Humidity. For automatic humidity control please see the H22 Brinsea Humidity Management Module.

Spot-Check Digital Thermometer
A very accurate, easily read instrument specifically designed for incubators with a range of 32° - 40°C (90º to 104ºF). Ten times more accurate than most digital thermometers, it reads to 0.1ºF with an accuracy of ± 0.2ºF. Switchable between ºF and ºC. Battery life is about 6 weeks in continuous use, but very much longer if switched on just as required........................................#HT-SDT-BP    $29.99**

Liquid in Glass Thermometer
Manufactured to Brinsea's specification, it covers the temperature range 25 - 40ºC (80 - 105 ºF) with high accurancy necessary for incubation use. ....................................................#HT-LGT-BP           $16.99 **

When disaster strikes and your developing chicks are threatened by any of the everyday problems listed above, the most important protection is for the breeder to be quickly made aware of the crisis.

If power failure happens in the middle of the night, the damage will have been done before morning, but in most cases action can be taken to protect the eggs, provided the user is alerted.

The Brinsea temperature alarm module offers immediate warning of change in temperature within an incubator. It relies on independent detection of temperature and includes an internal battery backup to allow the alarm to continue to sound in the event of a mains power failure. The high and low temperature limits are adjustable and in most cases the alarm can be set to go off if the temperature varies by 1.0ºF (0.5°C).

The module is available in two versions:

The T100 for fitting to Brinsea Octagon 100 or 250 incubators, only. The T100 has the additional feature of regulating temperature in the case of a failure of the main temperature control which could otherwise lead to uncontrolled temperature rise. In this case the T100 alarm will trigger and the heaters in the Octagon 100 series incubator are switched off. As the temperature then falls below the upper limit the heaters are switched on again and so reasonable temperature control is maintained.

The T20 can be fitted to any incubator or brooder. The T20 can be used to warn of temperature variation in any environment within its operating range of 77 - 104ºF range (25 - 40°C). The T20 simply requires its sensor to be inserted into the enclosure through a hole of about ¼ inch (6mm) diameter.

Both the high and low limits are easily adjustable with screwdriver operated trimmers. The system is flexible and allows the user to set the alarm sound if the temperature deviates by +1.0ºF or -3.0ºF (for example) from any temperature within 77 - 104ºF range.

A 'Silence Alarm' feature allows the sounder to be de-activated for about 10 minutes - useful when opening the incubator to check eggs. The sounder automatically resets after 10 minutes so there is no danger of the sounder being left inoperative by accident.

The internal battery backup allows the alarm to continue warning of a mains failure for several hours. The backup battery is automatically recharged when reconnected to the mains.

The T100 can be retro-fitted to Octagon 100 series incubators and fitting instructions are available.
