ATP PT-5035 4-in-1 Environment Meter
The ATP PT-5035 4-in-1 Environment Meter combines sound level, illuminance, relative humidity and temperature measurement in one portable instrument. It supports environmental spot checks across workplaces, facilities, offices, classrooms and other public spaces. A clear 28 mm LCD presents readings and function indicators for straightforward use during routine checks.
For sound measurements, users can select A or C weighting and work across a stated range of 35 to 130 dB. The separate light probe uses a cosine-corrected silicon diode sensor and measures illuminance from 0 to 20,000 lux. Data hold and maximum hold functions make it easier to retain useful readings while moving between measurement points.
The ATP PT-5035 4-in-1 Environment Meter also measures relative humidity and supports both ambient and contact temperature checks. An internal sensor and external K Type input provide temperature measurement options, while the supplied probes allow the instrument to be put to work across its stated measurement functions. Its handheld design, protective carry case, automatic power-off function and low-battery indication make it a practical choice for regular field, maintenance and inspection work.
Key Benefits
- Combines four environmental measurement functions in one handheld instrument, reducing the need to carry several separate meters.
- Selectable A or C sound weighting supports different sound level measurement requirements.
- A separate cosine-corrected light sensor helps provide reliable illuminance readings from different angles.
- Internal and external temperature inputs provide a choice of ambient and contact temperature measurement.
- Data hold allows a displayed value to be retained when it is useful to record or review a reading.
- Maximum hold helps capture and retain the highest measured value during a check.
- A clear 28 mm LCD with function indicators helps users view measurement information during testing.
- Two sound range settings allow the meter to be adjusted to suit the level being measured.
- Automatic power-off helps conserve the 9 V battery between periods of use.
- A low-battery indication helps users identify when the battery requires attention.
