Combustible Gas Detectors
A leak of natural gas (methane), propane or butane can cause an explosion in a basement with a sloppily installed unit as easily as it can in a coal mine. General sells these life-saving combustible gas detectors in various shapes and sizes, including pens and wands with a probe. Two models, the NGD268 & PNGD170 Combustible Gas Detectors even work from -40 to 158F, the extreme environment typical of mines and tunnel construction.

Heat Index Monitors
eat Index Monitors have the same two broad sets of applications: industrial (HVAC) and consumer monitoring the heat index, RH, dew point and wet-bulb temperature of an outdoor field for the purpose of improving player and worker safety. The industrial heat index monitors come in two sizes; the pocket-sized consumer versions do not.

Industrial Inspection Cameras
Industrial Inspection Cameras are our top-of-the-line inspection cameras. They feature glass lenses, superior optics, crystal-clear displays, and compatibility with the thinnest probes on the market. All Industrial Inspection Cameras were recently upgraded to capture VGA (640 x 480 pixel) resolution video clips and remove glare and reflections from them. All cameras in this sub-category are made in Taiwan, making them compliant with the Trade Agreements Act (TAA) of 1979a necessity for many buyers with the U.S. military and federal agencies.

Refractometers
Refractometers are used for two different applications: Measuring the sugar concentration of beverages and food, and measuring the salinity, specific gravity, refractive index or viscosity of industrial fluids such as oils, polymers, brake fluid and anti-freeze. Advanced models sport automatic temperature control (ATC). All have a metal body, cushioned eyepiece and rubber hand grip.

Tachometers/Torque Meters
Tachometers measure rotational or linear speed and come in two styles: contact and non-contact. Contact models come with various rubber/plastic adapters for interfacing the instrument’s shaft with the surface of the spinning or moving surface under test. Non-contact models come with reflective tape that is placed on the surface to become the target of the instrument’s low-power laser.

Thermocouple Thermometers
These industrial instruments’ claim to fame is their accuracy. General offers a wide variety of thermocouple thermometers distinguished by features such as the number of independent channels supported (from one to twelve) –such as the DT4208SD 12 Channel ThermoCouple Thermometer, ruggedness (the ability to survive a fall) – such as the Rugged DT62 Two Channel Thermocouple Thermometer, compatibility with one or more thermocouple types – such as the DT80-2 Two Channel “K” & “J” Thermocouple Thermometer, and data logging capability – such as the DT4947SD 4 Channel Thermocouple Thermometer with Excel Formatted Data Logging SD Card. Our portfolio of thermocouple probes is just as extensive.

Waterproof Inspection Cameras
waterproof inspection cameras have waterproof probes, General's DCS6XX wet/dry cameras, the DCS600A, DCS605, DCS660A, DCS665 & the DCS665-ART, go one step further because their grips and monitors are also waterproof. This feature, unique in the industry, allows users to inspect toilets and water and sewer lines carrying running water without worrying about dropping and "dunking" the instrument.

WiFi Inspection Cameras
WiFi Inspection Cameras generates a local WiFi hotspot (without Internet access) through which video clips and still photos of hard-to-reach or hard-to-see areas or equipment captured by the probe camera can be sent to an app-enabled smartphone or tablet for viewing and sharing. Free apps for iOS devices (iPhones or iPads) and Android devices are available from the iTunes App Store and Google Play Store, respectively. The three WiFi cameras differ in probe length, camera lighting and grip style.

Wireless Inspection Cameras
General offers three wireless inspection cameras whose probes can be disconnected from the grip and monitor. They are the DCS18HPART (with a 6mm/0.23 in. diameter articulating probe), the DCS1800HP (with a 5.5mm/0.22 in. diameter non-articulating probe), and the DCS500 (with a 9mm/0.35 in. diameter probe and a 5 in. diagonal color LCD). Wireless inspection cameras offer operating flexibility because the user can use both hands to manipulate the probe.

Moisture Meters
Moisture Meters fall into two categories, pin-type and pinless. Pin-type Moisture Meters measure the resistance between test pins inserted into a piece of wood or a building material and use that reading as a proxy for the object''s absolute moisture level. The wetter the material, the less ready it is to be sanded, painted, finished or covered. A best seller is the MMD4E Pin-Type Moisture Meter. Pinless Moisture Meters rely on the ability of moisture to inductively distort an electric field created by turning on the meter. Although Pinless Moisture Meters can only make relative readings, they are nonetheless useful for pinpointing the source of a leak above a ceiling, and for leaving no unsightly pinholes on a finished surface. The MMD7NP is a best selling pinless moisture meter.

Anemometers
Anemometer-Thermometer with Excel-formatted Data Logging SD Card and "K/J" Port accurately measures and logs speed and temperature of low-speed airflows in ducts, vents and other tight spaces.

product
Articulating Inspection Cameras
Articulating Inspection Cameras with probes whose tips can be precisely turned (articulated) by the user up to 150 in two directions. Articulation enables inspection of targets located off-axis (even "behind" the probe) or in a tight space without removing the probe. The Inspection Cameras currently offered include the DCS16HPART, its wireless cousin the DCS18HPART, and the DCS665-ART Articulating Inspection Cameras.

Infrared Thermometers
Two specifications tell you nearly everything you need to know about any infrared (laser) thermometer: its measurement range and its distance-to-spot (D:S) ratio. The wider the range and the higher the D:S number (a measure of its optical resolution), the better the instrument. Infrared Thermometers (IRTs) with lower numbers are perfectly adequate for simple tasks like spot-checking food temperatures and energy auditing such as the IRT207 Non-Contact Infrared Thermometer. Higher-priced infrared thermometers intended for industrial users may have a SKU that ends in "K" such as the IRT850K Ultra-Wide-Range Infrared Thermometer with K Port and Adjustable Emissivity. The "K" indicates that it can accept inputs from a "K" type thermocouple probe used to measure temperature on-contact.

Refrigerant Leak Detectors
refrigerant leak detectors use a proprietary semiconductor sensor to detect most commercially available HFC, HFO, HC, HCFC and CFC refrigerants. Our newest model, the RLD440 Refrigerant Leak Detector, goes one step further by complying with all five worldwide refrigerant detection testing standards
