Comparison with Competitors

Fluke 117 vs Fluke 115

Feature	Fluke 117	Fluke 115
Price	$200-250	$150-180
VoltAlert (NCV)	✅ Yes	❌ No
LoZ Mode	✅ Yes	❌ No
AutoVolt	✅ Yes	❌ No
True RMS	✅ Yes	✅ Yes
Capacitance	1000 μF	1000 μF
Temperature	❌ No	✅ Yes (-200-1090°C)
Best For	Electricians	HVAC technicians

Verdict: Fluke 117 worth $50-70 premium for electricians (VoltAlert + LoZ critical). Fluke 115 better for HVAC (temperature measurement).

Fluke 117 vs Fluke 87V

Feature	Fluke 117	Fluke 87V
Price	$200-250	$400-450
AC Voltage Accuracy	1.0%	0.7%
Frequency Range	50 kHz	200 kHz
Temperature	❌ No	✅ Yes
Min/Max Recording	Basic	Advanced (250 hrs)
Duty Cycle	❌ No	✅ Yes
Best For	Residential/commercial	Industrial/R&D

Verdict: Fluke 87V overkill for most electricians. Choose 87V only for industrial environments requiring ±0.7% accuracy or advanced logging.

Fluke 117 vs Budget Alternatives

Meter	Price	True RMS	NCV	Accuracy	Warranty
Fluke 117	$220	✅	✅	0.5% DC	Lifetime
Klein MM600	$80	✅	❌	0.5% DC	2 years
Amprobe AM-530	$120	✅	❌	0.5% DC	3 years
Extech EX330	$50	✅	❌	1.0% DC	2 years

Verdict: Budget meters save $100-170 but lack integrated NCV, LoZ mode, and Fluke's lifetime warranty/reliability.
