The Honeytek HK850+ Digital Sound Level Meter is a high-precision handheld instrument designed for accurate noise measurement in industrial, environmental, and occupational applications. Built for professionals such as safety engineers, facility managers, and environmental consultants, it delivers reliable real-time decibel (dB) readings across a wide measurement range.
With dual A/C frequency weighting, the HK850+ supports both human hearing simulation (A-weighted) and low-frequency/peak noise analysis (C-weighted)—making it suitable for workplace noise assessment, equipment monitoring, and compliance testing.
The device features a 6000-count backlit LCD display, ensuring clear visibility in low-light environments such as electrical rooms, factories, and field inspection sites. Combined with 2 samples/sec real-time data capture, users can accurately monitor fluctuating sound levels in dynamic environments.
Designed with durability and portability in mind, the compact 105g body includes a rubberized protective casing, making it ideal for daily field use. Additional features such as auto power-off, battery level indication, and data hold functions ensure efficient and uninterrupted operation.
The HK850+ is widely used for OSHA workplace safety compliance, ISO noise monitoring standards, environmental noise surveys, and building acoustics evaluation.

FAQ
Q1: What is the difference between A-weighting and C-weighting?
A-weighting reflects human hearing sensitivity, while C-weighting captures low-frequency and peak noise levels.
Q2: Is the HK850+ suitable for industrial environments?
Yes, with a 30–130 dB range and CAT-level durability, it is designed for industrial and field applications.
Q3: Can this sound level meter be used for compliance testing?
With ±1.5 dB accuracy, it is suitable for general compliance checks and reporting.
Q4: How often does the device update readings?
It samples at 2 times per second, ensuring accurate real-time monitoring.
Product Comparison: HK850+ vs. HK880F Digital Sound Level Meter
While both models serve the same core purpose—measuring sound levels—they differ significantly in features, size, and target users.
Summary:
The HK850+ is the premium, full-featured model ideal for professionals who need detailed data logging (Avg/MIN/MAX), battery monitoring, and maximum reliability. Its larger display and more powerful battery make it suited for extended fieldwork.
The HK880F is a compact, ultra-lightweight option perfect for quick checks, mobile inspections, or users prioritizing portability over advanced features. It lacks Avg/MIN hold and battery capacity display but retains core accuracy and durability.
