Spectra Precision HR320 Laser Receiver

Product overview

The Spectra Precision® HR320 Laser Receiver is a durable laser receiver for exterior leveling applications. LCD’s on the front and back display a 5 segment grade arrow that indicates grade position. A loud beeper is designed to be heard on noisy job sites. Fine and medium accuracies are selectable to meet various applications and conditions.

With two on-grade accuracies and dual LCD display, the Spectra HR320 Laser Detector extends the working range of your red beam rotary laser. This laser detector is ideal to use when estimating cut and fill, performing exterior leveling, or checking and setting elevations.

Selectable Grade Sensitivity

Featuring large, front and rear LCDs, the HR 320 laser receiver graphically displays easy-to-read information from different angles. It also has a five-segment arrow display that indicates grade position, 90-degree reception angle, and fine or medium selectable accuracies to meet various job site conditions.

Quickly Switch Applications

The included snap-on C59 rod clamp allows construction professionals to easily switch from rod-mounted to handheld applications. This Spectra laser detector also has a loud and adjustable 100-decibel speaker designed for noisy environments.

Built to Last

With an IP-67 rating, the HR320 is dustproof and waterproof and can withstand a five- foot drop onto concrete. It also works up to 70 hours using standard alkaline batteries and automatically shuts off after 30 minutes to save on power.
