The TRX335 uses a 384 × 288 thermal detector with a 12 μm pixel pitch.
This configuration is designed to capture differences in infrared energy and display them as a visible thermal image without relying on natural or artificial light.
Thermal-image performance depends on:
Target size
Temperature contrast
Weather conditions
Atmospheric humidity
Lens quality
Image processing
Display performance
Observation distance
The listed thermal sensitivity is 20 mK or lower.
A lower NETD value generally indicates an improved ability to distinguish small temperature differences, which may provide clearer detail in:
High humidity
Fog
Light rain
Low-contrast environments
Uniform backgrounds
Changing weather conditions
The exact test method, operating mode, and ambient conditions should be confirmed.
The 35 mm objective lens is intended to provide a balance between field of view, apparent magnification, and observation distance.
Before publication, confirm:
Lens aperture
Germanium-lens specification
Horizontal and vertical field of view
Minimum focusing distance
Optical magnification
Lens transmission
Protective coating
The listed magnification range is 3–12x.
Confirm whether this represents:
3x base magnification with 4x digital zoom
Continuous digital magnification
Fixed optical magnification with stepped zoom
Another optical and digital combination
Digital zoom enlarges the displayed image but does not increase the sensor’s native resolution. Visible detail may decrease at higher zoom settings.
The scope provides a listed detection range of up to approximately 1,800 m.
Detection means that a heat source may be visible. It does not necessarily mean that the subject can be recognized or positively identified at that distance.
Actual detection performance varies according to:
Target dimensions
Temperature difference
Weather
Humidity
Background conditions
Lens focus
Display settings
User experience
Recognition and identification ranges should be listed separately when verified.
The built-in laser rangefinder provides a listed measurement range of up to approximately 1,200 m.
Before publication, confirm:
Minimum ranging distance
Maximum ranging distance
Measurement accuracy
Laser classification
Single and continuous ranging
Measurement units
Angle measurement
Weather limitations
Target reflectivity requirements
The 1,200 m rangefinder specification should not be confused with the 1,800 m thermal detection range.
The integrated ballistic calculator is designed to generate calculated aiming references using entered equipment and environmental information.
Confirm support for:
Multiple saved profiles
Zero distance
Projectile velocity
Ballistic coefficient
Target distance
Temperature
Air pressure
Inclination angle
Sight height
MOA or MRAD output
Rangefinder data integration
Calculated outputs depend on correct input data, calibration, and environmental measurements.
The one-shot zeroing function is intended to simplify digital reticle alignment.
Before publication, confirm:
Freeze-frame support
Number of saved zeroing profiles
Number of distances per profile
Reticle movement increments
Profile naming
Restore-default function
Export or backup capability
The listed adjustment system uses MOA, with a 2 MOA aiming dot.
Before publishing, confirm:
Exact reticle pattern
Number of reticle options
Available reticle colours
Click value
Total horizontal adjustment
Total vertical adjustment
Saved reticle profiles
Reticle brightness settings
The specification “illumination: No” may simply mean there is no conventional illuminated optical reticle. Digital thermal reticles are generated on the internal display.
The device is listed as first focal plane.
Because this is a digital thermal system, the exact meaning should be confirmed with the manufacturer. Digital reticle scaling may be handled through software rather than a conventional physical focal-plane reticle.
Use “first focal plane” only when it appears in the official model documentation.
Side focus is listed as supported.
Confirm whether this control adjusts:
Objective-lens focus
Display focus
Parallax
Image sharpness
A combination of these functions
For a thermal device, objective focus and eyepiece diopter adjustment should be described separately.
The TRX335 supports video recording.
Before publication, confirm:
Video resolution
Frame rate
File format
Audio recording
Internal storage capacity
Maximum recording duration
USB file transfer
Date and time stamping
Automatic recording
Recoil-activated recording, if available
The internal display specification is missing.
Confirm:
OLED or AMOLED display
Display resolution
Screen size
Refresh rate
Brightness adjustment
Diopter range
Eye relief
Image sharpening
Noise reduction
Contrast controls
Display resolution should not be confused with thermal sensor resolution.
Confirm whether the device includes thermal palettes such as:
White Hot
Black Hot
Red Hot
Iron Red
Rainbow
Target Highlight
Edge Enhancement
Only verified firmware modes should be included in the final listing.
The device supports ten menu languages.
The exact included languages should be listed in the final specification, particularly when different firmware versions are supplied for different markets.
The listed IPX7 rating indicates resistance to temporary water immersion under defined laboratory conditions.
Before publishing, verify:
Exact tested model
Test depth
Test duration
Required port-cover positions
Battery-compartment sealing
Water-damage warranty terms
IPX7 does not include a certified dust-protection level.
The device is listed with impact resistance up to 800G.
This claim should be supported by test documentation specifying:
Test method
Impact direction
Number of cycles
Duration
Installed accessories
Lens configuration
Pass criteria
Battery information is missing from the supplied specifications.
Confirm:

Low-temperature runtime
Spare-battery availability
Actual runtime may vary with laser ranging, video recording, display brightness, wireless functions, and ambient temperature.
Confirm whether the standard package includes:
TRV TRX335 thermal imaging device
Rechargeable battery
Battery charger
USB cable
Lens cap
Eye cup
Carrying case
Cleaning cloth
User manual

Warranty exclusions
Avoid pointing the thermal detector directly at the sun, lasers, welding arcs, or other intense energy sources, as these may damage the sensor.
Use and installation must comply with the manufacturer’s instructions and all applicable local laws.
Keep the lens clean and dry, protect the device during transport, and inspect the housing, controls, battery, lens, and mounting components before use.
