INTRODUCTION

Thank you for purchasing General Tools & Instruments’ AQ150 In/Out Thermometer with Waterproof
Probe. Please read this user’s manual carefully and thoroughly before using the product.

The AQ150 has two separate temperature sensors: one inside the display unit and the other inside a
remote probe at the end of a 10 ft. (3m) long detachable cable. The remote circuit can be configured
to sound an alarm when the temperature it senses rises above or falls below a set limit. This
technology makes the AQ150 suitable for three different kinds of service:

• Maintaining the water temperature of an aquarium. In this application, the display unit is
magnetically attached to the frame of the aquarium and the remote probe is attached by
suction cup to the inside of a glass wall below the water level. The high and low alarms
would both be set to keep the water temperature within a band that is healthy for fish.

• Monitoring food temperature. The dual alarms make it possible to track the temperature
of a refrigerated case or heating table. Magnets on the back of the display unit could be used
to attach it to a metal part of the case or table. The high temperature alarm would be used to
guarantee that cold beverages and cold or frozen food remain that way. Use of the low
temperature alarm would ensure that hot food remains above a certain temperature, keeping
it safe to eat.

• Comparing indoor and outdoor temperature. The cable of the remote probe is thin
enough to fit under a window. A front panel switch lets you toggle the display between
INT (interior) and EXT (exterior) measurements.
