Troubleshoot Airflow, Temp & RH Problems with New Meter Series

Extech 510 Series Helps HVACR & IAQ Pros

New Meter SeriesOnline —  Extech recently announced the launch of several environmental meter series optimized for HVACR and Indoor Air Quality professionals.

The series includes an airflow meter, a combination hygro-thermometer and psychrometer, and a versatile 10-in-1 multifunction meter.

The new compact instruments are designed to provide quick, accurate readings on a range of environmental conditions that are essential for HVACR troubleshooting and repairs, as well as Indoor Air Quality (IAQ) assessments to improve occupant health and comfort.

The meters in the 510 series are equipped with a core set of shared capabilities and features to maximize versatility. The 510 meters share an informative, oversized display and a bright backlight for testing in dark job sites.

Useful data functions include data hold, as well as minimum and maximum readings. The Auto-Power-Off function preserves battery life and can be disabled for extended monitoring.

A wrist strap is useful for toting while a tripod mount lets users set up the meter with consistent placement to avoid variability in routine measurements (using an optional tripod, TR100).

EN510 10-in-1 Environmental Meter
The EN510 is a do-it-all environmental meter that can replace several HVACR meters, ensuring the right instrument is always available. The EN510 measures or calculates Air Velocity, Air Flow, Air Temperature, Bead Probe (Type K) Temperature, Heat Index, Humidity, Wet Bulb, Dew Point, Wind-chill, and Light Level.

An integrated mini-vane anemometer with low friction ball bearings ensures long-lasting and accurate air-related measurements. For humidity-related readings and calculations, a built-in capacitive humidity sensor ensures high accuracy.

Along with ambient air temperature, the meter also includes a general-use bead wire probe for temperatures up to ~480 °F (250 °C) while the meter itself is rated up to 2372 °F (1300 °C) with available probes.

Additionally, a precision photo diode measures light levels in Foot-Candles (Fc) or Lux, with cosine correction and a spectral response filter for color correction.

AN510 CFM/CMM Anemometer with Thermometer
Leveraging the same mini-vane anemometer design as the 10-in-1 meter above, the AN510 anemometer measures focuses on Air Velocity, Air Flow, Air Temperature and Bead Probe (Type K) Temperature.

The AN510 helps HVACR technicians troubleshoot problems such as hot and cold spots in a residential or commercial space; pressure imbalances; leaky ducts; or registers with little to no airflow.

The AN510’s dual display can display air and temperature readings simultaneously for added insights when performing IAQ thermal comfort studies.

RHT510 Hygro-Thermometer & Psychrometer
Similarly, Extech’s RHT510 offers the Temperature and Humidity diagnostic capabilities of the 10-in-1 meter. With the RHT510, a user can quickly assess not only Temperature (ambient and Type K) and Relative Humidity, but also Wet Bulb, and Dew Point. Wet Bulb measurements can be useful in troubleshooting evaporative cooling issues for example.

Dew Point measurements are ideal for controlling or adjusting indoor humidity. IAQ professionals can use dew points to target window condensation and related mold hazards for example.

Like the AN510, a dual display can indicate temperature along with a hygrometer/psychrometer reading at the same time.

All three meters are backed by a one-year warranty and come with three AAA batteries.

How to Order: Extech’s new environmental HVAC & IAQ meters are available now from Extech distributors around the world.

Omega’s IR Thermal Imager

Thermal Imager with Ethernet Connection for $1990 (US)!

Stamford CT, USA — While we were all sleeping, Omega Engineering one-upped just about everyone in the Infrared Thermal Imaging world. They dropped the price of their extremely low cost, 47 x 48 pixel, thermal imager (the OSXL-101) from $2900 to $1990!

Did you know that? Bet you didn’t! Did you even know they had a Thermal Imager in their vast larder of gadgets? Above is part of a shot from their online tutorial showing four separate images from four OSXL-101s connected to one PC monitoring station. That’s pretty advanced in OHO! (more…)

A Social Network at ExTech

Plus a Real Blog From The Infrared Training Center (ITC)

Southampton PA, USA –??We said in an article a few days ago there was no blog at Extech Instruments website or at the Infrared Training Center (ITC) website. We were right and wrong. Extech doesn’t have a real blog, yet, that?? we could see without joining up by proffering our email address and birthdate.

They have what they call a Social Network and it might have a blog inside a firewall. You have to sign up to see what Extech has beyond a few “teasers” on the home page! We don’t consider that a blog, nor do most Web geeks.

The blog we found at BlogSpot run by Mr. Gary Orlove of the ITC is certainly a blog. (Thanks for reminding us about it, Gary, we ‘d overlooked it, somehow.) The IR InformIR ( is a real blog but with a few quirks! (more…)

Uncooled IR Cameras & Detectors

Market Report: NEW Uncooled IR Cameras & Detectors for Thermography and Vision

Lyon, France — Initially developed for the military market by US defense companies, use of uncooled infrared (IR) cameras in commercial applications has been growing over the last ten years. In the infrared spectrum, Long Wave Infrared (LWIR) is the most commonly used wavelength (8-12 microns). Thermography and a variety of vision enhancement applications are the main growth markets for uncooled IR cameras.

This camera cost reduction will continue through 2015 in the thermography business and will also be a strong factor in the vision market (also called night vision or vision enhancement) with the growth of the security/surveillance and automotive markets.

Driven by the continued cost reductions, the volumes of camera sold will triple by 2015 from more than 200,000 cameras today to more than 700,000 units, meaning +23 % annual growth rate. The revenue growth will be about + 9% as market prices for the cameras decrease. (more…)
