Fluke's 87V, 175, and 179 are the three most frequently purchased professional multimeters in Singapore across M&E contracting, industrial maintenance, and building services. All three share Fluke's rugged build, CAT III 1000 V / CAT IV 600 V safety ratings, and True RMS measurement. Yet they serve different professionals in different ways.

Fluke 175: Best for Singapore Licensed Electricians
The Fluke 175 is the practical workhorse for Singapore's Licensed Electrical Workers doing LV installations and testing distribution boards. Its 6,000-count display delivers resolution adequate for most site work. The 0.09% DC accuracy exceeds most LV testing requirements. The 700-hour battery life means it runs through months of daily site use without fresh batteries — a practical advantage on long M&E projects.
What the 175 lacks: no temperature input (no Type K thermocouple) and the high-resolution 20,000-count display of the 87V. For standard electrical installation and commissioning work, these omissions are irrelevant. Buy the 175 if your work is primarily LV electrical installation and testing.
Fluke 179: Best All-Rounder for HVAC and Building Services
The Fluke 179 adds a Type K thermocouple temperature input to the same 6,000-count platform as the 175. This one addition makes it the preferred choice for HVAC technicians in Singapore who need to measure refrigerant line temperatures, supply and return air temperatures, and motor winding temperatures — all with a single instrument. Battery life at 400 hours is lower than the 175 but still practical. Buy the 179 if your work spans both electrical and HVAC/mechanical with integrated temperature measurement.
Fluke 87V: Best for Industrial Engineers and VSD Commissioning
The Fluke 87V is in a different class. Its 20,000-count display provides 3× more resolution than the 175/179 — enabling readings like 230.12 V where the 175 shows 230.1 V. The 0.05% DC accuracy matters for calibration verification and precision measurements. The 1 ms peak hold is critical for capturing transient spikes on VSD outputs — a common task in Singapore's heavy manufacturing and process industries.
The 4,000-segment analogue bar graph responds at approximately 40 readings/second, excellent for adjusting potentiometers and locating minima/maxima by watching the bar graph trend. Singapore semiconductor fabs, pharmaceutical manufacturers, and data centres routinely specify the 87V. Buy the 87V if you commission VSDs, servo systems, UPS equipment, or do precision process instrumentation work.
Decision Summary
- Buy the Fluke 175 — standard LV electrical installation, testing, commissioning; battery runtime priority; no temperature needed.
- Buy the Fluke 179 — HVAC/building services; integrated temperature measurement with Type K; 6,000-count resolution adequate.
- Buy the Fluke 87V — VSDs, servo drives, precision instrumentation, calibration verification; 20,000-count and 1 ms peak hold are genuine requirements.
