Description
Product Overview
The KAISAL 2-in-1 digital tachometer merges two measurement technologies in a single handheld device. It features a high‑definition backlit LCD that remains clear in bright workshop lighting or dark maintenance bays. The unit supports a wide speed range—1 ~ 19 RPM for direct contact probes and 9 ~ 99,999 RPM for laser non‑contact measurement—providing flexibility for rotating shafts, fans, and light‑source flicker frequency checks. Built with a durable ABS housing, the tachometer weighs just one pound and measures 9.53 × 4.09 × 2.01 in, making it easy to carry in the included portable bag.

Usage
Designed for industrial, scientific, and hobbyist environments, this tachometer excels in machine maintenance, HVAC fan testing, motor diagnostics, and laboratory light‑source analysis. The contact probes allow direct attachment to shafts, while the laser sensor enables safe, non‑contact readings on moving parts or delicate equipment. Its auto‑power‑off after 15 seconds of inactivity conserves battery life, making it suitable for field service technicians and on‑site engineers who need reliable performance without frequent recharging.

FAQ
Can the laser measurement be used on reflective surfaces?
Yes, the built‑in photo sensor is calibrated to handle a variety of surface finishes, including polished metal and painted surfaces, delivering accurate RPM data without physical contact.
How often does the device need calibration?
KAISAL tachometers are factory‑calibrated and maintain accuracy for up to two years under normal use. Re‑calibration is recommended only after heavy impact or exposure to extreme temperatures.
What batteries does the tachometer use?
The unit operates on a single AA alkaline battery, providing up to 200 hours of continuous use before the low‑battery prompt appears.
Is the data exportable?
While the tachometer stores peak values internally, data can be manually recorded. Future firmware updates may add Bluetooth connectivity for wireless export.
Can I use the device for measuring light‑source flicker frequency?
Absolutely. The laser sensor detects flicker frequencies, making it suitable for checking LED and fluorescent lighting stability.
