Thermo-Anemometers/Dataloggers

SDL300/SDL310/SDL350 Thermo-Anemometer/Dataloggers

Three models to choose from with different sensor size and design to either
withstand high temperature environment or measure low level air velocity

SDL310

• Datalogger date/time stamps and stores readings on an SD
card in Excel

• Selectable data sampling rate: 1 to 3600 seconds (1 hour)

• Manually store/recall up to 99 readings

• Type K/J Thermocouple input for high temperature measurements

• Large (9999 count) LCD displays Air Velocity and Temperature simultaneously

• Record/Recall MIN, MAX readings

• Data Hold plus Auto power off with disable function

• Complete with 6 x AA batteries, SD card, sensor with 3.9ft (120cm)
cable, and hard carrying case; (See
Type K and J Thermocouple probes); 3 year warranty

SDL300 Metal Vane Additional Functions

• 2% velocity accuracy via low friction ball bearing vane wheel on 39" (1m) cable

• Metal Vane withstands temperatures to 158°F (70°C) and air velocity to 6900ft/min

SDL310 Vane Additional Functions

• 2% velocity accuracy via low friction ball bearing vane wheel on 39" (1m) cable

• Measures Air Temperature to 122°F (50°C) and air velocity to 4930ft/min

SDL350 Hot Wire Additional Functions

• Air Velocity meter with telescoping probe designed to fit into HVAC
ducts and other small openings and can read down to 40ft/min

• Probe extends up to 7.05ft (215cm) maximum length with cable

Vane Versus Hot Wire

Which sensor type should you choose?
For many technicians, it is ultimately a
matter of preference but there are some
distinguishing factors to keep in mind.
Vane anemometers are very useful for
fast, accurate measurements of air
velocity. The ultra compact size of a hot
wire anemometer probe makes it easy to
access small openings such as louvered
vents. Telescoping hot wire probes are also
useful for reaching high locations.
