Sit and Reach Tester

Sit-and-Reach Tester

Standalone Unit:
1. Automatically measures the sit-and-reach value, reflecting the flexibility and extensibility of joints, muscles, and ligaments in the torso, waist, hips, and other areas.
2. Comes with a dedicated testing mat (not a yoga mat).
3. Main Technical Parameters:
Measurement Range: -20cm to 35cm
Graduation Value: 0.1cm
Measurement Accuracy: ±0.1cm
Main Unit:
1) The main unit uses an industrial-grade CONTEX-M3 CPU for direct control of underlying hardware, independently developed with full intellectual property rights. It runs on a closed 32-bit proprietary encrypted operating system, ensuring system stability and security while avoiding interference from public network viruses. It is a closed-source system with instant boot-up and is not based on Android.
2) The main unit features dual-chip storage for data backup, with a storage capacity of 60,000 to 120,000 records. It provides full-process voice prompts (adjustable volume and option to turn off prompts). The main unit uses a 7-inch color touchscreen display system with adjustable backlight brightness (the screen is touch-enabled, allowing all functions to be operated via the touchscreen).
3) The main unit (standard configuration) includes an audio interface for external speakers for amplification. It has charging indicator lights and a USB insertion indicator function.
4) The main unit has ≥2 USB ports. It (standard configuration) includes a built-in imaging QR code and barcode scanner (for quick entry of tester information). It optionally supports built-in non-contact IC card and ID card functionality. The main unit (standard configuration) supports USB interface barcode scanners for quick entry of tester information. It supports mechanical key input for test numbers (and also supports full keyboard input via the touchscreen for entering test numbers containing digits or letters). The main unit (standard configuration) supports batch import of tester information via USB drives for rapid "roll-call testing." It features an incremental function for test number entry to facilitate quick and easy information input.
5) The main unit uses a menu-driven, WYSIWYG interface with full-process voice prompts (adjustable volume and output capability) for user-friendly operation, requiring minimal training for independent use. Operators do not have permission to delete test data; only administrators have data management privileges to ensure data security.
6) Data networking is fully wireless, enabling real-time or batch transmission. It uses 2.4G communication (for long-distance, large-scale networking). The high-power, high-frequency wireless communication module offers long transmission range, strong diffraction and penetration capabilities, and large network capacity. The wireless communication forms a closed-loop local self-organizing network, avoiding interference from public network viruses. The 2.4G module for networking has an experimental transmission range of up to 2 kilometers in open areas.
7) The main unit uses silicone keys with a long service life. It features a 4*5 matrix 20-grid multifunctional key design, tested for 100,000 cycles of durability and fatigue performance to ensure key labels remain clear and intact. The keys also have anti-slip properties to prevent mispresses due to finger slippage.
8) It supports dual power sources: DC/AC. It includes a built-in high-capacity lithium battery, providing over 10 hours of continuous operation, with full-process battery level indicators on the display.
9) The main unit is versatile, allowing users to select and instantly pair with any peripheral via menu keys and touchscreen operation, enhancing reusability and reliability. It operates without connecting to a computer and can switch between any test items without modifying the main unit’s program. All peripheral communication with the main unit uses the ANT 2.4G communication protocol.
10) Test result data from the main unit can be quickly exported to a USB drive and imported into physical test data management software on a PC (avoiding long waits for batch uploads and the issue of PCs not being near the device for batch data collection).
