Recently, we released an article explaining some of the reasons that distributors should carry thermo-hygrometers (a.k.a. RH meters) for their customers—reasons such as ASTM F-2170 testing, helping to improve restoration work, optimizing lumber production efforts, and because it makes distributors a true one-stop shop for their customers’ moisture testing needs.
However, it’s also important to stock the right kinds of thermo-hygrometers for your customers’ relative humidity (RH) testing needs. Which RH meters are the best ones to carry for your customers? Well, the answer to that question depends on your customers’ needs. With this in mind, here’s a list of some of Delmhorst’s best portable humidity meters.
RH Meter #1: HT-3000
The HT-3000 thermo-hygrometer is a great portable humidity tester that emphasizes providing ease of operation and accuracy. This digital RH meter has a clear, bright display to make reading it easy in all lighting conditions
This RH meter can measure temperature over the range of -4˚F to 158˚F (-20˚C to 70˚C)—more than enough to accurately monitor temperatures in most worksite conditions throughout the USA. The Grains Per Pound (GPP) range for this meter is 1 GPP to 2,000 GPP. Using the two measurements combined allows the meter to accurately measure the relative humidity of a given area with ease.
The RH meter’s price is economic for such an accurate and reliable tool—making it useful for your budget-conscious contractor and home inspection customers. Combined with the digital RH meter’s ease of use, its price and functionality make it an ideal tool for first-time users—whether they’re homeowners or new employees of a restoration, building inspection, or wood manufacturing company.
RH Meter #2: HT-4000
The HT-4000 is a direct upgrade over the HT-3000 in almost every way. Its GPP range is broader than the HT-3000 (0.1 GPP to 3,820 GPP). Additionally, it can monitor ambient temperature over the range of -40˚F to 255˚F (-40˚C to 124˚C). This thermo-hygrometer also possesses a vapor pressure measurement feature that can monitor vapor pressure over the range of 0-7 PSI (0-47 KPA).
The backlit screen makes it easy to read even in dark areas, and the RH/T sensor is simple to remove and replace as needed to keep the RH meter as accurate as possible. Overall, this is a top-tier portable humidity meter for monitoring RH conditions as well as conducting ASTM F-2170 testing.
RH Meter #3: TotalCheck 3-in-1
Where the other two devices on this list are purely thermo-hygrometers, the TotalCheck is a 3-in-1 device that combines the functions of an RH meter with both pin and pinless moisture meters. The thermo-hygrometer function of this moisture testing device is every bit as capable as the HT-4000, but with a few additional capabilities thanks to the integrated pin and pinless moisture meters.
This device is perfect for restoration experts who want to be able to carry a complete moisture testing solution with them wherever they go on the job. The pin meter uses a wood scale with built-in species corrections for 69 different types of wood to make it highly flexible, while the scan (pinless) meter uses a reference scale mode to make getting quick positive/negative indications of moisture easy in a wide range of materials. Also, the meter can record up to 1,400 readings with date and time stamps—a must-have for users who have to document their moisture measurements!
The extra functionalities of the TotalCheck make it an expert’s device that is worth every penny of the RH meter’s price. Many restoration specialists use them to quickly track down moisture intrusion sources in a building or to pinpoint the exact area and severity of a moisture pocket in various building materials.
Which RH Meter is the Best for Your Customers’ Needs?
If you need an all-in-one moisture testing solution so your customers don’t have to buy, maintain, and carry three separate devices, the TotalCheck may be the ideal tool for their needs. However, if you need a top-quality RH meter that emphasizes ease of use for less experienced users because you have a lot of DIY customers or companies that need to train up new employees, then the HT-3000 may be the perfect solution.
The HT-4000 provides top-quality relative humidity testing capabilities in a single specialist device, and its compatibility with in-situ probes makes it a must-have for testing moisture in concrete—which is why many flooring installers and construction contractors have come to rely on this tool.
Basically, the answer to which of these thermo-hygrometers you should stock as a distributor depends largely on the customers in your market.
