Multi-Function Anemometers
TA460 Series

The TA460 series are portable, hand held, Multi-Function Thermal Aneomometers. They are designed to measure air velocity, differential pressure, temperature, and humidity. Calculations include air flow, wet bulb, dew point, and turbulence. The instruments are compatible with a range of optional probes that have a versatile choice of features and functions.

Features and Benefits
• Accurate air velocity measurement
• Optional ‘smart’ plug-in probes, including CO2, rotating
vane probes, and VOC (volatile organic compounds)
• Data logging and downloading software included
• Fast calibration and repair service


Rotating Vane Anemometers
Model LCA301
Model LCA301 is a light weight, robust, and simple to use Rotating Vane Anemometer that provides accurate and reliable readings every time. Ideal for HVAC commissioning at grilles, ducts, and diffusers; the LCA301 displays readings in metric or imperial mode.

Features and Benefits
• Reversible 100 mm head allows readings at supply and extract grilles
• Calculates volumetric flow rate
• Compatible with Aircone Flow Hoods
• No density correction factors required
• Automatic averaging of air velocity


Added Features
• Calculates volumetric flow rate in duct from velocity and user-input duct size and shape
• Records data points in duct traverse using sampling function
• Data logs up to 12,700 samples and 100 test IDs with time and date stamp
• Includes LogDat2 downloading software

Micromanometers
Models PVM620
The PVM620 is a rugged, compact, comprehensive Micromanometer that measures pressure, and calculates velocity and volumetric flow rate. It can be used with Pitot tubes to measure velocity and then calculate flow rates with user–input duct size and shape. Premium features make it ideal for HVAC, environmental safeguards, commissioning, process control and system balancing.
The PVM610 is an easy to use, hand held digital Micromanometer for fast, accurate and reliable pressure measurement. It can also calculate velocity.

Features and Benefits
• Measures differential and static pressure from –3735 to +3735 Pa
• Calculates and displays velocity when using a Pitot tube


Pitot Static Tubes
Choose from a comprehensive range of Pitot Static Tubes offering telescopic, fixed length, and jointed tubes to suit virtually any application. Also available are “S” type Pitots for restricted access and hostile environments and Pitots with adjustable mounting glands for permanent installations. The Thermo–Pitot Static Tubes with integral thermocouple sensors allow combined in-line pressure and temperature measurement. Manufactured from a high grade stainless steel, all Pitots are durable and tolerate aggressive conditions. They are suitable for sensing in heating, ventilation, and air conditioning equipment including commissioning and troubleshooting.

Features and Benefits

• Totally compatible with manometers, pressure gauges, and transmitters
• Use for COSHH assessment and environmental monitoring
• Excellent accuracy, K–factor 0.997
• Excellent yaw and pitch characteristics
• Spring slip markers for insertion
• Direction pointer to ensure correct alignment
