How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Choose refrigerant compatibility before battery endurance

A convenient battery setup is useful only after the detector and required sensor suit your refrigerant and work environment. Read the exact refrigerant list and operating instructions first. Fieldpiece offers rechargeable configurations, while CPS Products and Yellow Jacket also have replaceable-battery configurations; those power choices cannot certify detection suitability.

Weight is supported for 9 products, with values spanning 380 to 500 g. Most maker weight bases are unspecified, while a Fieldpiece entry explicitly includes batteries. UEi lacks usable weight and runtime values, so an active preference cannot treat that unknown information as a measured value.

Carry the runtime qualifier into the comparison

CPS Products claims over 50 hours of continuous use for its C-battery configurations. A rechargeable Fieldpiece configuration gives 18 hours typical with backlight off. Yellow Jacket AccuProbe II Leak Detector gives 4.5 hours continuously. The manual phrases describe different conditions rather than a shared endurance measurement; no leaks were sought with the instruments for this comparison.

For a long service visit, decide whether rechargeability or spare batteries suit your routine, then review the runtime note for that specific detector. Do not use battery life or weight as a substitute for sensor suitability. Manufacturer pages can refer you to dealers, so their presence alone does not confirm stock or checkout availability.

Before you buy

Will either work with my refrigerant?

Read the current refrigerant list, required sensor and exact operating instructions. Battery, runtime and weight cannot establish compatibility. Fieldpiece DR58 weighs 400 g with rechargeable lithium-ion and a typical 18 hr runtime with backlight off. CPS LS1 weighs 500 g with three C batteries. Conditions differ. DR58 suits you if that rechargeable setup matters. Weight bases vary; start with refrigerant and sensor compatibility rather than interpreting runtime as comparative performance.

Can I compare every runtime directly?

CPS LS1 claims over 50 hr of continuous use. Yellow Jacket AccuProbe II claims 4.5 hr continuously; Fieldpiece uses different conditions. Keep each maker’s qualifier and weight basis.

Which model has missing portability details?

UEi RLD15B has no runtime or weight here, and its battery chemistry is unspecified. An active runtime or weight preference excludes it rather than treating the missing value as zero.

Do the manufacturer pages establish stock?

Some exact model pages refer buyers to dealers. Stock and checkout availability are not confirmed; confirm the current offer with the seller.
