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.
KEY FEATURES • Displays ambient or remote (INT or EXT) temperature • Tracks MAX and MIN temperatures • High and low temperature alarms for remote circuit • ºC/ºF button • Backlit LCD and detachable cable of remote probe • Foldaway stand and magnets on back of display unit • Includes battery and mounting hardware • CE approved WHAT’S IN THE BLISTER PACK The thermometer comes in a blister pack along with: • A remote probe at the end of a detachable cable • A suction cup for mounting the probe inside an aquar

To activate the thermometer, open the battery compartment in the back of the unit (Fig. 2, Callout 12) by lifting the left side of the hinged door with your fingertip. Remove the battery activation tab. The beeper will sound quickly four times. Discard the tab and swing the battery compartment cover shut. CHOOSE A TEMPERATURE UNIT Before proceeding, remove the protective plastic film covering the display. Then turn the unit over and press the red °C /°F button (Fig.
To detach the unit (to change the battery, change the temperature unit, or reset the high and/or low alarm limits), grab it and pull until the two Velcro strips separate. EXTEND AND SECURE THE PROBE Remove the twist tie keeping the probe cable in a bundle. Extend the probe cable to the desired length. To install the remote probe in an aquarium, 1) Slide the probe tip through the hole in the base of the suction cup. 2) Press the suction cup firmly against the glass inside the aquarium about 4 in.
OPERATING INSTRUCTIONS DISPLAYING REAL-TIME TEMPERATURE To display the ambient temperature at the display unit, press the Ext/Int button until INT appears at the right of the readout. To display the temperature sensed by the probe, press the Ext/Int button until EXT replaces INT. DISPLAYING MAX AND MIN TEMPERATURES Pressing the Max/Min button briefly (for less than 1 second) cycles through three readings: maximum, minimum and real-time temperatures.
SETTING HIGH AND LOW TEMPERATURE ALARMS Temperature alarms can only be set for the sensor in the external probe. You cannot set alarms with the display unit mounted on a wall or frame because setting alarm levels requires access to the °C /°F button on the back of the unit. Before proceeding, detach the unit by pulling it off the metal frame or separating the Velcro mounting strips. 1. To set either or both alarms, begin by pressing the button and holding it for 3+ seconds.
3. To set the low temperature alarm limit, follow the instructions in Step 2 on previous page, subtituting “low” for “high” and “decreases/decreasing” for “increases/increasing.” 4. When the desired low and/or high temperature alarm level(s) is/are displayed, press the button to store the setting(s). Once you have stored the high and/or low alarm temperature level(s), the display will stop flashing and resume showing the Int or Ext temperature it was showing when the alarm setting process began.
