Minus 40 to 85 degrees, accurate to 0.2, for every species.
Temperature-sensing microchip, minus 40 to 85 C at ±0.2, full FDX-B ID. QR pet tag in the box. Plus registry plan included in the price.
Our highest-specification microchip: full ISO FDX-B identification plus a temperature sensor that reads from minus 40 to 85 degrees Celsius at plus or minus 0.2 degrees. Built for veterinary, breeding, research and exotic-species work. Plus registration and a QR pet tag are included.
ThermaSenseX extends the ThermaSense idea in both directions. The sensing window runs from minus 40 to 85 degrees Celsius (minus 40 to 185 Fahrenheit), and accuracy tightens to plus or minus 0.2 degrees (0.36 Fahrenheit). That range covers reptiles basking under a lamp, aquatic species, livestock in winter, and every mammal in between.
Identification stays fully standard: ISO 11784/11785 FDX-B on 134.2 kHz with a unique 15-digit number, readable by any universal scanner. Temperature readings need a ThermaSenseX-compatible reader; that separation keeps the medical-grade readings out of casual hands.
The chip is rated for 30 years of service after implantation, with a five-year shelf life sealed in its sterile pouch. The capsule is bioglass with an anti-migration coating, EO gas sterilized, and passive throughout: no battery, nothing to charge, nothing to fail.
This listing is the 2.12 by 12 mm size. A 1.4 by 8 mm mini exists for very small species; contact us if your work needs it.

Like every chip we make ourselves, ThermaSenseX includes the Plus registry plan in the base price: lifetime registration, universal lookup, 24/7 recovery support, live assistance.
Every United Pet Club chip registration starts with Essential, which is free for the life of the pet: the registration itself, the universal lookup, and email alerts when your pet's number is scanned. Plus adds 24/7 recovery support and live assistance. Deluxe adds unlimited profile updates, travel document storage and priority support. Complete is a single payment that switches on everything we offer. Upgrades are one-time purchases, not subscriptions, and you can add one at any point after registration.
The with-implanter format is a sealed single-use unit. Needle-only clicks into a reusable implanter and brings the per-chip cost down for colonies, clinics and field programs. Same chip in both.
Implantation is a quick injection under the loose skin between the shoulder blades, and it belongs in trained hands. Veterinarians, registered breeders, shelter staff and technicians place chips every day; some regions also allow trained owners, others require a professional, so check your local rules. If you are unsure, buy the chip, bring it to your next appointment, and have the clinic place and log it in one visit.
The minus 40 to 85 degree window and 0.2 degree accuracy make ThermaSenseX usable as a low-stress data point in studies where handling skews the numbers. Packs of 20, 50 and 100 carry per-chip included registrations and pack pricing.
Range and precision. ThermaSense reads 30 to 55 degrees Celsius at plus or minus 0.3, enough for warm-blooded pets. ThermaSenseX reads minus 40 to 85 degrees at plus or minus 0.2, which adds reptiles, aquatic species, livestock in extreme climates and research use.
For the ID, yes: it is a standard FDX-B chip on 134.2 kHz. The temperature function answers only to ThermaSenseX-compatible readers.
Yes. The sensing window was chosen for exactly that: a basking reptile can sit far above mammal temperatures and a pond fish far below, and both stay inside the minus 40 to 85 degree range.
It is rated for 30 years in the animal, which outlasts every companion species it would be placed in. Sealed shelf life is five years.
Yes. The Plus plan is part of the base price, with Deluxe and Complete as optional one-time upgrades.
This listing is 2.12 by 12 mm, the standard companion-animal size. The 1.4 by 8 mm mini suits very small or juvenile animals; ask us about it if your program needs the smaller needle.
No. It is passive and reports only when a reader asks. Logging over time happens in your records or in the United Pet Club app.
The capsule and coating are the same medical-grade bioglass system used across our chips, placed with a standard injection. For very small species, consider the mini size and have a professional place it.
