Import 3-In-1 Digital Luxmeter Tl-601 — Buy in Bulk from Supplier in China

The 3-in-1 Digital Luxmeter TL-601 from Dongguan Xinrui Instrument Co., Ltd. combines illuminance, temperature, and relative humidity measurement in a single handheld unit. The device measures light intensity in both lux and foot-candle units, temperature in Celsius and Fahrenheit, and ambient humidity as percentage relative humidity. The TL-601 targets agricultural monitoring, building energy audits, and laboratory environmental control where simultaneous tracking of multiple parameters reduces instrument count and field logistics. The digital display and push-button interface suggest a portable, battery-powered form factor typical of entry-to-mid-range environmental meters manufactured in the Dongguan instrument cluster.

Sensor architecture for this product category typically employs a silicon photodiode with cosine-correction diffuser for illuminance, a thermistor or semiconductor junction for temperature, and a capacitive polymer element for humidity. Standard lux measurement ranges for comparable 3-in-1 meters span 0 to 50,000 lux or 0 to 5,000 foot-candles, with resolution of 1 lux and accuracy of ±4% to ±5% of reading plus digit count. Temperature accuracy is commonly ±1.0°C to ±1.5°C across 0°C to 50°C, and humidity accuracy ±3% to ±5% RH across 20% to 80% RH. The TL-601 likely uses a single PCB with dedicated ADC channels per sensor, LCD driver, and microprocessor for unit conversion and display formatting. Power is typically from a 9 V battery or AAA cells, with auto-power-off to conserve battery life during intermittent field use.

Buyers include agricultural greenhouse operators monitoring crop light exposure and microclimate, facilities managers optimising HVAC performance against daylight harvesting, and research technicians documenting experimental conditions. The dual-scale display supports international teams without manual conversion. Wholesale purchasers should confirm whether Dongguan Xinrui Instrument Co., Ltd. supplies calibration certificates traceable to national standards, the sampling rate for each parameter, and whether data-hold or min/max logging functions are included. Packaging is typically individual gift box with manual and battery, master carton of 20 to 50 units. Given the 0.00% response rate, buyers should establish direct contact to confirm lead time, sample availability, and whether OEM firmware customisation is offered for private-label programmes.

Dongguan Xinrui Instrument Co., Ltd. is based in Dongguan, Guangdong Province, China, with the address listed as Dongguan, 523710. The supplier carries a harbour trust tier, indicating a foundational level of platform verification. The response rate is recorded as 0.00% with zero average response hours, which signals no tracked engagement through platform messaging. Buyers should not rely on platform-mediated communication alone and should seek direct contact through the provided address or external channels to establish supplier responsiveness before committing to orders.

The company profile does not disclose year of establishment, registered capital, factory floor area, employee count, annual turnover, or export markets served. No certifications such as ISO 9001, ISO/IEC 17025, or CE marking documentation are confirmed in the available data. Dongguan is a major hub for electronics and instrumentation manufacturing, which provides Xinrui with access to component supply chains and skilled assembly labour, but this regional advantage must be balanced against the need for direct supplier verification. Buyers should request a company brochure, factory video, or third-party audit to supplement the minimal disclosed information.
