NEW! Testo Pocket Pro

The Testo Pocket Pro meters are mini-powerhouses of measurement capability for the on-the-go HVAC and building maintenance person. The Testo Pocket Pro instruments include:

• Air Velocity - vane anemometer
• Temperature - material/surface (IR) and air
• Optical tachometers - RPM
• Humidity and dew point
• Light intensity - Lux, Foot-candle
• Pressure, differential pressure, absolute pressure
• Material moisture - wood, composites, concrete
• Borescope with video output

Testo 435 family of instruments can monitor and record critical Indoor Air Quality parameters using wired and wireless probes to monitor atmospheric CO₂, air velocity, relative humidity (dew point), temperature, absolute pressure, differential pressure and illumination intensity. In its most sophisticated configuration the instrument system datalogs to a PC or connects via IrDA to a thermal printer for onsite data analysis.

This instrument is ideal for taking velocity in FPM (0 to 8,000 fpm), volumetric flow measurements in CFM (volume flow calculation 0 to 999,999 CFM) and temperature readings (-58.0 to 300.0 °F). The Testo 435 anemometer can average readings over time or at a number of positions and easily calculate volumetric flow in CFM, m3/sec, m3/hr, etc.

More than 10 different probes are available for use with the Testo 435 family of instruments.

The Testo 521-526 series multifunction meter with the built-in micromanometer is configured for differential pressure measurements in the HVAC range of 0 to 40" wg (0-100 hPa), e.g. pressure drops across filters or inspection of fans or extraction equipment. The meter has nine user selectable display pressure units: in H₂O, mbar, hPa, bar, Pa, kPa, mm H2O, torr and psi. Flexibility is enhanced as additional probes can be connected to Testo 521-526 pressure meters via 2 user defined probe socket.

The Testo 535 is the easiest way to measure CO2 for indoor air quality (IAQ) surveys. Poor air quality in rooms can lead to tiredness, lack of concentration and illness (Sick Building Syndrome) due to high CO2 concentration (greater than 1000 ppm)

The Testo 317-3 CO meter detects the presence of carbon monoxide (CO) in ambient air from gas furnaces, water heaters, and other appliances or equipment and signals the user of dangerous gas concentrations with both visual and audible alarms.

The Testo 545 light meter can quickly check lighting levels and can quantify the luminous intensity in the workplace, hospitals, offices or schools.  It can verify if the lighting meets specific minimum guidelines.  A location list with individual values can be saved and later connected to form a curve using software.  This “light profile” provides information on the uniformity of the lighting.

Thermohygrometers

Testo 625 thermohygrometer simultaneously displays temperature and %RH or dew point - suitable for monitoring work-area comfort conditions, IAQ parameters, HVAC and manufacturing areas requiring humidity and temperature control. Monitor for conditions that lead to mold/fungus growth. Probe configuration options include using the probe head on a cable and extended handle, and a wireless probe for locations which are difficult to monitor when the system is operating.

Testo Digital Manometers

The Testo 512 portable digital manometer series includes four different versatile pressure and velocity meters. When connected to a Pitot tube, the Testo 512 PDM simultaneously displays pressure and air velocity. Testo 512 meters display 6 switchable pressure units: hPa/mbar, mm H2O, mm Hg, psi, in H2O and in Hg; 2 switchable velocity units, m/s and fpm; ±0.5 % full-scale value / ± 1 digit and integral density compensation. Testo 512 PDM meters are perfect for use in measuring differential pressure across filters and coils in HVAC systems, monitoring positive and negative pressure in air conditioning ducts, and measuring differential pressure for clean room monitoring.  

The Testo 521 multifunction meter has a built-in micromanometer and is configured for differential pressure measurements in the HVAC range of 0 to 40" wg (0-100 hPa), e.g. pressure drops across filters or inspection of fans or extraction equipment. The meter has nine user selectable display pressure units: in H₂O, mbar, hPa, bar, Pa, kPa, mm H₂O, torr and psi. Flexibility is enhanced as additional probes can be connected to Testo 521/526 pressure meters via 2 user defined probe sockets.

The Testo 526 series multifunction pressure meters have an operating range from 0 to 80" H2O (0 to 2000 hPa) and are designed for industrial applications, where critical processes require measurement and monitoring with accuracy up to 0.05 % of full scale value.

Borescopes

The Testo 318 borescopes are a series of lighted, fiber optic scopes which use an integrated focus ring to ensure smooth continuous operation while focusing The TestoView 318 fiberscopes are perfect for use as a flexible tool for inspection of inaccessible areas as they have a high powered lens which clearly focuses on objects as close as 3/4" while a integrated powerful LED illuminates dark areas with the simple push of a button. The TestoView 318 Series fiber optic borescope's revolutionary flexible shaft adjusts into almost any position. Typical applications for the TestoView 318 Series Fiber Optic borescopes include mold and mildew investigations behind walls, diagnosing blocked air conditioner evaporator coils (the hidden cause of many overcharged systems) and examining heat exchangers from the inside out. Plus, it can be used for feeding thermostat wires, checking for ductwork clearance and many other daily HVAC and industrial tasks. The TestoView 318 borescopes are available in 18", 36", 48", 72" and 96" flexible wand tip lengths.
