It’s that time of year again when the hum of air conditioning units fills the hot air. It’s also the time that many people realize they need a service call because the a/c just isn’t cooling. One of the first things checked is the refrigerant level to see if there is a leak. Every technician needs a refrigerant leak detector, and at Stromquist we recommend Testo’s 316 Refrigerant Leak Detector.
Testo’s highly accurate and reliable refrigerant leak detector is the only modular leak detector for all standard refrigerants and ammonia (it easily converts to ammonia detection by swapping out the sensor). The sensor status is monitored continuously and alerts the user to malfunctions or contamination. Technicians can save time that is usually wasted taking sample leak tests. If the sensor is dirty, it can be electronically cleaned and then is immediately ready for use. When a leak is detected, the display changes from green to red and provides an audible alarm. Testo also provides and earplug to hear the alarm in loud surroundings.
The unit has an adjustable sensitivity to help pinpoint leaks and has a 14.5″ flexible gooseneck to help with optimum positioning of the sensor. The sensitivity is calibrated to R134a, R22, R12 R404a and Hydrogen. It detects CFCs, HCFCs, HFCs (including 410a) and blended refrigerants, and the response time is less than one second. The solid-state sensor technology is backed by a 2-year warranty.

Do you ever need to track temperatures or humidity levels in a certain space for an extended period of time? Sometimes taking just one reading doesn’t give you a big enough picture; that’s when a data logger comes in handy. UEi, a leading manufacturer of testing and monitoring equipment, has a great data logger on the market. It’s small, inexpensive, easy to use, and doesn’t require the purchase of software to download the data.
It has a magnetic mount that makes it easy to “hide,” and it can log up to 32,000 data points (16,000 temperature and 16,000 humidity). The temperature range is -40 to 158 degrees F, and the humidity range is 0 to 100% . You can select your sampling intervals to be anywhere from 2 seconds up to 24 hours, and you can set values that will trigger the built-in LED alarm. It is Windows compatible with a USB interface, so when you are finished gathering your data, you simply plug it in to the USB port of your computer to download the information. The included software allows you to chart your results, calculate dew points and export the data to other file formats. It operatates on a 3.6v lithium battery and has a one-year limited warranty.
