Field Diagnostic Instrumentation

Comparing Thermal Resolution and Safety Ratings for the Field Engineer.

NEC Wire Gauge Calculator

Calculates voltage drop based on NEC Chapter 9, Table 8 Resistance.

Recommended Wire Gauge (Copper) -- AWG
Based on 3% max voltage drop.

Thermal Imaging: Resolution War

Model Thermal Resolution Refresh Rate Engineering Verdict
FLIR TG267 160 x 120 (19k pixels) 9 Hz Best for generalists. MSX tech makes low-res images readable.
Hikmicro B20 256 x 192 (49k pixels) 25 Hz Best Value. 2.5x more thermal data than FLIR for the same price.

Hikmicro B20

For the technical buyer who wants raw data. The 256x192 resolution provides superior detail for PCB analysis and electrical panels.
