The Klein Tools CL800 was a mid-priced AC/DC True-RMS clamp meter that a lot of electricians and HVAC techs carried. It is no longer listed in Klein’s clamp meter catalog, and Klein now sells the CL810 in that slot. This page is here so that anyone searching for the CL800 finds the replacement and the alternatives.

Specs at a glance
Best for: Techs who want a durable 600 A clamp with capacitance at a mid price tier.
- 600 A AC/DC, auto-ranging, True RMS
- Voltage, resistance, continuity, frequency and capacitance
- Non-contact voltage detection in the jaw
- 6.6 ft drop rating and IP40 ingress protection
- Lighted dial and reverse-contrast display
Why it stands out
- 600 A AC/DC range with capacitance
- Built-in non-contact voltage detection
Keep in mind
- No microamp range listed, so it is not a flame-sensor clamp
Fieldpiece SC680 Wireless Swivel Clamp Meter with Power
Best for: Commercial and VFD-heavy techs who want one wireless clamp that also logs to the Job Link app.
- 600 A AC/DC swivel clamp with inrush
- True-RMS with low-pass filter for VAC and Hz (VFD work)
- Power (kW) measurement; phase rotation test
- Dual Type K temperature inputs; resistance to 50 Mohm; NCV
- CAT IV 600 V / CAT III 1000 V
Why it stands out
- Swivel jaw, AC/DC amps with inrush
- Low-pass filter for accurate readings on VFD outputs
- Two temperature inputs for delta-T
- High safety rating: CAT IV 600 V / CAT III 1000 V
Keep in mind
- About 100 h battery life on a 9 V, less with wireless and backlight
- Heavy at about 480 g and long at 301 mm
UEi DL389B Dual Display True-RMS HVAC Clamp Meter with Temperature
Best for: Residential HVAC techs who want a single clamp for amps, flame sensors and big start capacitors.
- 400 A AC (jaw); no DC amps listed
- AC/DC microamps to 2000 uA via test leads
- Capacitance to 4000 uF; resistance to 40 Mohm
- Temperature -22 to 752 F
- 1000 V DC / 750 V AC; True-RMS
Why it stands out
- 4000 uF capacitance covers large start capacitors
- Microamps for flame sensors
- Temperature input
- Dual display
Keep in mind
- AC amps only on the jaw
- CAT III 600 V, no CAT IV rating
What happened to the CL800
Klein’s current clamp meter catalog does not list the CL800. The Amazon listing for it still exists, and the title lists auto-ranging True-RMS, AC/DC voltage and current, LoZ, continuity, frequency and capacitance. Confirm any other figures on the listing.
If you already own a CL800, nothing about it has stopped working. If you are buying new, buy the model Klein currently sells.
The Klein CL810, the CL800’s successor
According to Klein’s catalog, the CL810 is a 600 A AC/DC True-RMS clamp with LoZ, inrush, DC microamps, 6,000 uF capacitance, temperature, non-contact voltage and a 1.4 in jaw. It is rated CAT IV 600 V / CAT III 1000 V. That is a fuller HVAC feature set than the CL800 title lists, because DC microamps and temperature are the two functions an HVAC tech needs most from a clamp.
Search Amazon for the CL810 by model number and check that the title says CL810 before you buy.
What to buy instead right now
- Residential service work: the UEi DL389B lists 400 A AC amps, 2,000 uA microamps on the leads, 4,000 uF capacitance and temperature.
- Commercial and variable-speed work: the Fieldpiece SC680 lists 600 A AC/DC, inrush, a low-pass filter and a CAT IV 600 V / CAT III 1000 V rating. Read the SC680 review.
- A simple amp clamp: the Fluke 323 is a True-RMS AC clamp that pairs with the Fluke 116.
How to compare any HVAC clamp meter
Check five things on the spec sheet before you buy: amp range and whether it reads DC, microamps through the leads, capacitance range, a temperature input, and the CAT rating. If the spec page does not list one of them, assume the clamp does not have it until a manual says it does. See the full clamp meter guide.
Frequently asked questions
Is the Klein CL800 discontinued?
It is not listed in Klein's current clamp meter catalog, and Klein's CL810 sits in the same slot. Amazon may still show listings from third-party sellers.
What replaced the Klein CL800?
The Klein Tools CL810. Klein lists it as a 600 A AC/DC True-RMS clamp with inrush, DC microamps and temperature.
Can the CL800 test a flame sensor?
Klein lists DC microamps on the CL810. Check the CL800 listing for a microamp range before relying on it for flame sensors.
