  • TypeAdjustable Wrenches
  • Measures up to 40 m with ±2 mm accuracy

  • Rechargeable 180 mAh battery delivers about 3 000 measurements
  • Switches between metre, foot and inch units instantly

Purpose & User

The Hetai Tech LS-1 is a pocket-sized digital rangefinder built for indoor layout work. It suits decorators, designers and tradespeople who need quick distance, area or volume readings without a tape measure. The single-button operation keeps the workflow simple on site. It is not for buyers who need outdoor surveying range or data-logging features.

Build Integration

The aluminium-alloy body weighs 28g and slips into a shirt pocket or tool pouch, freeing belt space for other kit. A USB-rechargeable 180mAh cell delivers about 3000 measurements per charge, so the tool stays ready through a full refit without a spare battery. The Class 2 laser (620–670nm, <1mw) operates safely in occupied rooms. It is not for builders who require tripod mounting or Bluetooth data export.

Sustained Operation

The LCD backlight stays legible in low-light conditions during extended measuring sessions. Rated for 0°C to 40°C operation and –20°C to 60°C storage, the unit maintains its ±2mm accuracy across the 0.03–40m span even after repeated use. The iF Design Award 2019 recognises the durable, lightweight construction. It is not for users who need continuous scanning or environmental sealing beyond the stated temperature limits.
