Today I will be going over the TSI 9515 VelociCalc Air Velocity Meter. This meter is an excellent entry level air velocity meter for the professional HVAC technician. The TSI 9515 separates itself from the plethora of air velocity meters in this price range by having a range of 0 to 4,000 ft/min (0 to 20 m/s) and an accuracy of 5%.

Last week I wrote about the TSI HM675 Hydronic Manometer . Today I will be discussing its older brother the TSI HM685 Hydronic Manometer.  The HM685 manometer is an upgrade over the HM675 and has the same features but with a few upgrades. First the HM685 can calculate flow, heat flow, impeller diameter and brake power. This unit is also a data logger and stores up to 4,000 data points on the internal memory that can be used with the provided CompuDat Downloading Software.

Testo 310, 320, 330 older models are available as new generation products: Testo 310 II Combustion Analyzer, and Testo 320 Combustion Analyzer. 

It appears that logic and common sense has prevailed. In an announcement that seemed all too obvious, TSI Alnor has released a few new accessories for their TSI Alnor EBT731 Balometer. This includes a wheeled stand that can extend up to 15ft in the air and LogDat Mobile software that can be used via Bluetooth to operate the Balometer and see data, take pictures, record voice annotations and generate reports.

Finding a quality hydronic manometer can be a tough task. However, the TSI HM675 Hydronic Manometer is great choice. The HM675 can simultaneously measure and display low side, high side, and differential pressure. This unit also has a nice splash-proof case and inputs for two temperature probes. The HM675 reads pressure in H2O, ft H2O, psi, in. Hg, m H2O, kPa, mm Hg, bar and has a range of 0 to 300 psi. Great for setting balancing valves, checking pump performance, and balancing heating and cooling systems.

The Testo 870-2 is no longer in production.

The “hot” (pun intended) new section of the thermal imaging marketplace is point-and-shoot entry-level cameras, and manufacturers are eager to offer cameras that have an excellent intersection of price and features. The new Testo 870-2 offers just this – high end features within a reasonable budget.

The Testo 870-1 is no longer manufactured.

The new Testo 870-1 Thermal Imager is designed to provide competition to the entry level cameras of other manufacturers; and while it does do this, it also includes some features that set it apart from the entry level market.
