1. What NxTHERM is
NxTHERM is a fast, clinical-grade, Bluetooth digital thermometer built to integrate with the NxVET ecosystem. The device supports 5–10 seconds readings and stores 10 memories. It runs on a CR2032 battery, and is IP27 rated.
NxTHERM supports a 32.0–43.9°C (89.6–111.0°F) measuring range, ±0.1°C / ±0.2°F accuracy (in the clinical band), dual °C/°F, beeper, and waterproofing.

4. Quick start (standalone temperature reading)
Step-by-step
Clean the probe (see Cleaning section).
Press On/Off to power up.
Place probe in the chosen measurement site and keep it still. Movement can cause errors and longer measurement time.
Watch the display while (---) flashes; when it stops, the thermometer beeps (~10 seconds) and shows the reading.
Record/confirm the value; the unit will typically auto-power off (behavior can vary by firmware).
5. Choosing a measurement site
What the base device is designed for
NxTHERM is designed for oral, rectal, and underarm (axilla) readings and not for ear use. Practically, that means surface/contact sites where you can get consistent contact and reduced fur interference.
These are the most workable “stress-free” contact sites or temperature without rectal insertion:
Axillary/“armpit” area (front leg against chest wall)
Inguinal fold (inner thigh/groin crease)
Note: Underarm readings are medically less precise than core temperature.
So the safe way to deploy NxTHERM clinically using the stress-free contact sites is:
Use NxTHERM for fast screening + trending, and
Confirm critical decisions (hypothermia/hyperthermia cases) with a gold-standard method per your clinic SOP.
6. Selecting modes (Oral / Underarm / Rectal / Bath)
NxTHERM supports:
Adjusted modes: Oral / Rectal / Underarm
Direct mode: Bath
How to change mode
Power on the thermometer.
While the mode is displayed, press and hold On/Off until the mode flashes.
Press again to cycle through the four mode options.
Stop pressing and wait; it auto-enters measurement mode.
NxTHERM clinic default suggestion: Use Underarm mode for stress-free pet readings.
7. Switch Celsius ↔ Fahrenheit (THIS is the key step you asked for)
To change NxTHERM to °F:
Turn the thermometer OFF.
Press and hold the On/Off button for ~3 seconds.
The unit toggles the setting (°C ↔ °F).
Confirm the symbol in the upper-right of the LCD.
8. Memory (view last readings)
The base device stores the last 10 memories.
View saved temperatures
Power on.
While the last reading is displayed, press and hold On/Off to enter Memory Mode.
Press to cycle through stored readings.
Long-press On/Off for ~3 seconds to exit.
9. Using NxTHERM with NxVET via Bluetooth
NxTHERM supports Bluetooth syncing using:
NxHUB
NxVET Android or iOS app
Details on this will be updated shortly, please contact support@nx.vet for early access.
If NxVET doesn’t pick it up (fast checklist)
Confirm NxTHERM has a fresh battery (low battery icon / inconsistent powering).
Confirm you’re within 1–10 meters and ideally not surrounded by lots of other BLE devices.
Take a new reading (some devices only transmit after measurement completes).
Force-close/reopen NxVET app; toggle Bluetooth off/on.
10. Cleaning & disinfection (clinic-grade)
After each patient
Wipe probe and body with a clean soft cloth and remove visible soil.
Then disinfect using one of the platform-approved approaches:
Method B (low-level; most practical in clinics):
Use 70% medical alcohol on a soft cloth, wipe the probe 3 times, ≥1 minute each time.
Method A (high-level):
Immerse probe in 0.55% OPA (e.g., CIDEX OPA) ≥12 minutes at 68°F.
Don’ts (avoid damage)
Don’t use strong solvents (benzene, paint thinner, gasoline).
Don’t soak in alcohol/OPA/hot water for long periods; avoid hot water >122°F/50°C for long time.
Don’t ultrasonic-clean.
11) Battery replacement (CR2032)
Replace when the low-battery indicator appears.
Use a coin in the battery cover slot; rotate to open.
Remove old battery with a non-metal tool; insert new CR2032 with positive side up; rotate cover back to lock.
12) Calibration & QA
Factory calibration is done at manufacture; periodic readjustment isn’t required if used properly.
13) Troubleshooting (common issues)
Reading takes “too long”
High temperatures can take longer; the manual notes predictive measurement can exceed 15 seconds in some situations and suggests retesting and minimizing movement.
Ensure good contact pressure and reduce fur interference.
“Err” or strange readings
If device errors, remove the battery, wait 1 minute, reinstall (power cycle).
If temperature is below 32.0°C/89.6°F or above 43.9°C/111.0°F, the device will indicate out-of-range and you should retake under better contact/rest conditions.
Low battery / random shutdown
Replace CR2032.

15) Safety notes
For veterinary clinics specifically:
Treat NxTHERM as a medical instrument—keep away from chewing pets and small children (battery hazard).
If you are using non-rectal sites for “stress-free” readings, use it as a screening/trending tool unless you have validated correlation to core temperature in your SOP.
