Welcome. Today, we'll be reviewing the Fieldpiece JL3KM2 Dual Port Manometer Probe Kit with Job Link Connectivity for Measuring Static, Gas, and Draft Pressure.

The Fieldpiece JL3KM2 is an accurate and versatile dual-port manometer probe kit that includes two manometer probes, which work independently and are not constrained by hoses, allowing for the simultaneous measurement of return static, supply static, and total external static pressure.

Additionally, these probes can measure the draft and gas pressure in a furnace.

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.

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.
