Let’s Dive into Extech Instruments Psychrometer + Ir Thermometer
The Extech Instruments Psychrometer + Ir Thermometer, model HD500, is a 3-in-1 tool designed for professionals who need to accurately measure humidity, contact temperature, and non-contact temperature. Made by Extech Instruments, this device combines the functionality of a humidity meter, a Type K thermometer, and an infrared (IR) thermometer into a single, rugged unit. It boasts a large triple LCD backlit display, a built-in USB port, and several useful features like minimum/maximum readings, data hold, and auto power off.
I needed a reliable way to monitor environmental conditions in my workshop, which sees temperature and humidity fluctuations throughout the year. My old analog hygrometer was simply not cutting it, and I required more precise and versatile measurements. The Extech Instruments Psychrometer + Ir Thermometer caught my eye because it promised accurate readings across multiple parameters, allowing me to fine-tune my environment for optimal tool storage and project outcomes.
Upon unboxing, I immediately noticed the solid build quality of the Extech Instruments Psychrometer + Ir Thermometer. The double-molded housing feels robust and ready to withstand the rigors of daily use. It’s a bit heavier than I anticipated, which gives it a reassuringly substantial feel, but the weight is well-distributed, making it comfortable to hold.
Compared to similar devices like the Fluke 975 AirMeter or the Testo 625 Thermohygrometer, the Extech Instruments Psychrometer + Ir Thermometer stands out for its integrated IR thermometer and included USB connectivity at a more competitive price point. While those models offer comparable accuracy and features, the Extech provides a more complete package for the cost. I chose this model because of its versatility and the promise of seamless data logging capabilities.
My first impression was one of excitement tempered with a bit of apprehension. I was eager to put the Extech Instruments Psychrometer + Ir Thermometer through its paces and see if it lived up to the specifications, but I also hoped that the menu system wouldn’t be too complex. The triple LCD display and numerous buttons initially seemed a bit daunting.
Real-World Testing: Putting Extech Instruments Psychrometer + Ir Thermometer to the Test
First Use Experience
I first tested the Extech Instruments Psychrometer + Ir Thermometer in my workshop, which is a detached building exposed to the elements. I wanted to get a baseline reading of the ambient temperature and humidity, as well as surface temperatures of various tools and materials. The device performed admirably in this initial test.
The Extech Instruments Psychrometer + Ir Thermometer handled the fluctuating conditions of an early spring day with ease. I tested it in the morning when it was cool and damp, and again in the afternoon when the sun had warmed things up. The readings were consistent and seemed accurate when compared to a calibrated reference thermometer I had on hand. Using the type K probe, I measured contact temperatures, and the IR thermometer allowed me to assess surface temps from a distance.
The Extech Instruments Psychrometer + Ir Thermometer was relatively easy to use straight out of the box. The menu system is intuitive enough, although I did need to consult the manual to fully understand all the functions. It took about 30 minutes to familiarize myself with the settings and learn how to toggle between different measurement modes.
The only initial issue I encountered was related to the IR thermometer. I realized that the distance-to-spot ratio required a bit of practice to get accurate readings on smaller objects. Once I adjusted my technique, however, the results became more reliable.
Extended Use & Reliability
After several months of regular use, the Extech Instruments Psychrometer + Ir Thermometer has proven to be a reliable and valuable tool. It continues to provide consistent and accurate measurements. I use it almost daily to monitor the conditions in my workshop, greenhouse, and even during outdoor projects.
The rugged housing has held up well to the demands of my work environment. There are no visible signs of wear and tear, despite being subjected to occasional bumps and drops. The buttons still feel responsive, and the LCD display remains clear and easy to read. The double-molded housing is definitely a key feature to its overall durability.
Maintaining the Extech Instruments Psychrometer + Ir Thermometer has been simple. I occasionally wipe down the housing with a damp cloth to remove dust and dirt. The Type K probe is easily cleaned as well, and so far, I haven’t needed to replace the battery.
Compared to my previous hygrometer, the Extech Instruments Psychrometer + Ir Thermometer is in a different league. It provides much more comprehensive and accurate measurements, and the data logging capabilities are a game-changer. The ability to track environmental trends over time has allowed me to optimize conditions for my projects and equipment.
