Case with 4 Digital Meters for Environmental Measurements

Case with 4 Digital Meters for Environmental Measurements

The metal case is padded with custom cut foams to hold a series of digital meters — four modern, ergonomic instruments for environmental measurements:

• Digital Sound Level Meter, 30..130 dBA
• Lux Meter 0…200,000 lx with min and max function
• Electronic Wind Speed Anemometer with Temperature Measurement
• Relative Humidity and Air Temperature Meter

Detailed descriptions of the meters are provided below. All meters can also be purchased separately. The set is housed in a metal case with reinforced corner protection and a comfortable handle measuring 39 x 10 x 28 cm. The interior of the case is lined with two foam inserts cut to the exact size of the instruments to protect the meters during transport and storage.

With the set we can measure:

• sound level (30…130 dB) /dBA = scaled to the human ear sensitivity curve/
• illuminance (0…200,000 lx)
• relative humidity of air plus air temperature (-10°C…+50°C; 10…99%)
• air flow velocity and its temperature (0…90 km/h; -10…+45°C)

DETAILED SPECIFICATIONS for each instrument:

Digital Sound Level Meter, 30..130 dBA
The digital sound level meter features a multi-level LCD display (3 ½; digit height 10 mm), enabling quick and easy measurement of sound intensity in the range of 35…130 dB(A). This corresponds to measurements based on the audible perception of sound by the human ear (the A‑weighted curve reflects the ear’s response). The decibel meter has two measurement modes — fast (125 ms) and slow (1 s). It is factory calibrated and is particularly suitable for measurements in educational and work environments. Accuracy: ±1.5 dB. Resolution: 0.1 dB. Frequency range: 31.5 Hz…8.5 kHz. Auto calibration: 10 s. Microphone: 1/2 electret. Low battery indicator. LED backlight for the display activates automatically in low ambient light. Powered by a 9 V battery (included). Includes windscreen. Operating temperature/humidity: 0 - 40°C / 10–80% RH. Compact, ergonomic, and modern housing. Compliant with IEC 651 Type 2 and ANSI S1.4 Type 2 and 2011/65/EU. Tripod mountable (not included). Dimensions: 55 x 135 x 35 mm; weight: 120 g.

Lux Meter 0…200,000 lx with min‑max function
Illuminance meter with a multi‑level LCD display (3 ½; digit height 10 mm) provides quick (sampling at 1.5x/s) and easy measurement of illuminance in three ranges: 0…2000 lx / 20,000 lx / 200,000 lx. Min and max value indicator. Factory calibrated (color temperature: 2,856 K). Compact, ergonomic, modern housing. High‑speed photodiode sensor (sampling rate 1.5x/s). Especially recommended for measurements in educational and work environments as well as environmental measurements. Measurements in Lux or lm/ft². Accuracy: ±4% of reading for <10 klx; ±5% for >10 klx. Resolution: 1 lx (2000), 10 lx (20000), 100 lx (200000). Sampling 1.5x/s. DATA HOLD function (freezes the reading on the display). LED backlight automatically activates in low ambient light. Powered by a 9 V battery (included). Low battery indicator. Auto shutoff after 10 minutes of inactivity. Operating temperature/humidity: 0 - 50°C / <80% RH. Compact ergonomic housing. Compliant with 2004/108/EC and 2011/65/EU. Tripod mountable (not included). Dimensions: 55 x 155 x 35 mm; weight: 120 g.

Electronic Wind Speed Anemometer with Temperature Measurement
Electronic wind speed meter measures airflow in various units: m/s, km/h, and feet per minute (ft/min), knots, and miles per hour. It also measures air temperature (°C or °F) and displays both values simultaneously on a multi‑level LCD display (3 ½; digit height 10 mm). Pressing a separate button shows the average and maximum values. Compact, ergonomic, modern housing. Factory calibrated. Accuracy: ±5% for airflow; ±2 °C; ±3.6 °F for air temperature. Measurements: 1.5/s. Ranges (for m and °C): 0…30 m/s; -10…45 °C. Low battery indicator. LED backlight automatically activates in low ambient light. Powered by a 9 V battery (included). Auto shut off after 10 minutes of inactivity. Operating temperature/humidity: -10…45 °C / <80% RH. Compliant with EU directive 2004/108/EC. Tripod mountable (not included). Dimensions: 55 x 155 x 35 mm; weight: 120 g.

Relative Humidity and Air Temperature Meter
Humidity and air temperature meter, electronic, with a multi‑level LCD display (3 ½; digit height 10 mm), enables quick and easy measurements in indoor environments such as homes, workplaces, schools, and facilities such as greenhouses. Measurement ranges: 10%…99% RH; -10…50°C. Factory calibrated. Compact, ergonomic, modern housing. Relative humidity accuracy: ±3% at 25°C; 30…90% RH; ±5% at 25°C; 10…30% RH. Resolution: 0.1% RH; 0.1°C. Sampling 2x/s. Low battery indicator. LED backlight automatically activates in low ambient light. Powered by a 9 V battery (included). Auto shutoff after 10 minutes of inactivity. HOLD function to freeze the displayed value. Operating temperature/humidity: -10…40°C / <99% RH. Compact ergonomic housing. Compliant with 2004/108/EC and 2011/65/EU. Tripod mountable (not included). Dimensions: 55 x 145 x 35 mm; weight: 158 g.

All of the contents are securely packed in a metal latch case with corner protectors and a comfortable handle measuring 39 x 10 x 28 cm, with interior fitted with two foam inserts cut to match the instruments.
