Technical advice
on product selection
01 / How they work
Each field on the strip corresponds to a specific temperature. Once that temperature is reached, the field turns permanently black — the evidence remains on the strip, even after cooling. No maintenance, no calibration.
THERMAX 10-point · range A
— °C

Progi: 37 · 40 · 44 · 46 · 49 · 54 · 60 · 62 · 65 · 71 °C
Monitoring of equipment, bearings and installations in the 37–71 °C range.
THERMAX 8-point · range A
— °C

Progi: 37 · 40 · 43 · 46 · 49 · 54 · 60 · 65 °C
Washing, pasteurisation and equipment temperature monitoring in the 37–65 °C range.
THERMAX 6-point MINI · range 8
— °C

Progi: 241 · 249 · 254 · 260 · 280 · 290 °C
High-temperature processes and industrial installations: 241–290 °C.
Heating simulation — the fields turn black in sequence and do not return to their original colour.

Transport protection
Indicators attached to the packaging show whether a shipment has been dropped, struck or tipped over. The recipient can see this immediately — no batteries required and no need to open the package.

Impact
The window turns red when the impact threshold is exceeded — sensitivities from 5G to 75G. The QR version records the inspection when scanned with a phone.
ShockWatch impact indicators →
Tilt
Permanently indicates whether cargo has been tilted beyond the permitted angle or tipped over. For control cabinets, machinery and equipment that must remain upright in transit.
TiltWatch tilt indicators →
Large loads
For transformers, machinery and oversized cargo — records impacts with date and time throughout transit.

Select a monitoring area to see typical components and recommended Thermax temperature indicator strips — from 1 to 10 levels, covering 25 to 300 °C.
Components to monitor
Combat vehicle operation and diagnostics
Indicators applied to wheel bearing housings, final drives, drive axles, main transmissions and gearboxes on tanks and armoured vehicles (e.g. KTO Rosomak, AHS Krab, BWP Borsuk, K2 and M1A2 Abrams tanks). A sudden temperature rise signals a lubrication fault or component wear before the equipment becomes immobilised in the field. Additional applications include monitoring brake discs and callipers, and checking the surfaces of engine blocks, turbochargers, power packs and exhaust systems for hot spots.
Weapons, ammunition and missiles
Monitoring heat build-up in artillery and small-arms barrels during intensive firing helps prevent ammunition cook-off in the chamber, as well as excessive barrel wear and deformation. Strips on ammunition boxes and guided missile containers confirm that critical temperatures for explosive stability and sensitive guidance electronics have not been exceeded.
Military aviation, helicopters and unmanned aerial vehicles (UAV)
Monitoring helicopter gearboxes, jet engine components and avionics compartments. Indicators show whether an electronic module has operated above the temperature permitted by the manufacturer's specification (MIL-STD-810H). In reconnaissance and strike platforms (UAV, UGV, USV), they monitor electronic speed controllers (ESC), brushless motors and Li-Ion/LiPo battery packs operating under heavy loads and at high ambient temperatures.
Radar, communications and optoelectronics
Monitoring passive and active cooling in military radios, radar modules (including AESA antennas), electro-optical sensor heads and thermal imagers. Applications also include monitoring heat build-up in lithium battery packs used in soldiers' portable equipment and electronic warfare systems.
Standards compliance and environmental resistance
Military applications use versions compliant with NATO / STANAG requirements, the MIL-STD-810H environmental standard and the ISO 9001 quality management system. Versions resistant to gear oils, hydraulic fluids, aviation fuel (NATO F-34 / JP-8), water and UV radiation are available. Thermax strips are available in multi-level versions (including 5-, 8- and 10-level strips), covering a range from 25 °C to 300 °C.
Zero signature — tactical security
The indicators operate entirely passively: they have no batteries and emit no radio-frequency radiation or additional heat, so they do not increase equipment detectability by signals intelligence (SIGINT) systems or thermal imaging. They are also unaffected by electromagnetic pulse (EMP), and a technician or soldier can read them at a glance during an inspection.

03 / Applications
Self-adhesive Thermax temperature indicators and strips offer a reliable, cost-effective solution wherever electronic thermometers, wired sensors or thermal imaging cameras are too expensive, difficult to install or impossible to use.

01
Passive temperature monitoring for combat vehicles, gun barrels, ammunition, avionics and drones — no power supply or signal emissions.

02
Thermal loads on brakes, engines and turbochargers during track testing and everyday operation.

03
Early detection of overheating bearings, gearboxes and motors — before downtime occurs.

04
Monitoring busbar connections, contactors, transformers and photovoltaic installations.

05
Verifying soldering processes and detecting hot spots on components.

06
Accurate temperature measurement on coated parts and monitoring of coating curing.

07
Temperature uniformity in injection moulds and monitoring of vulcanisation processes.

08
The effects of hot exhaust gases on aircraft skin and extreme temperatures in landing gear brakes.

09
