Finding the right Cable Certifier can be quite time intensive. There are many options out there and it can get confusing. Today I will be talking about the Ideal Industries 33-993 LanTEK II series Cable Certifier. This particular model is the 1 GHz bandwidth version which is the top end of their offerings (the other models being 350 and 500 MHz respectively). The LanTEK II series of Cable Certifiers have a few neat features that differentiate itself from the pack.

With the weather beginning to change, the “Combustion Season” is again upon us. It’s time to analyze your old equipment and see what needs to be replaced. A new CD100A Combustible Gas Detector by UEi would be a great addition or replacement to your existing equipment. This detector is lightweight and can be used with one hand. There is an option for a headphone jack as well which can help if you are in a congested area or working in a noisy environment.

Everybody loves a sale! However, the new pricing for Extech Oscilloscopes goes way beyond your normal 10 to 20% off kind of thing. We’re talking darn near half price for the same great units that used to cost a fortune. The Extech MS6060, Extech MS6100, Extech MS6200 are all drastically reduced in price saving the customer $600-$900 just off the list price.

The UEi C155 Combustion Analyzer is a no nonsense analyzer that gets the job done. This analyzer can measure temperature (20-2400 F), CO2 (0-20%), CO (0-2,000ppm). The C155 uses a CO2 sensor and the CO measurements to calculate the O2 present which increases the shelf life of the sensors. This change eliminates the need for the O2 sensor which in turns eliminates your need to send it in for replacement every year.

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 320 - discontinued

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 Thermal Imaging Camera hs been discontinued.

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.
