LKK423 Voice Digital Hammer ( Schmidt Hammer ) Introduction:

Voice Digital Hammer (Schmidt Hammer) in line with GB / T9138-1988 standards and procedures and JJG817-93 JGJ / T23-2011 technical specification. This product is suitable supervision company, Quality Supervision and Inspection Center site sampling tests to use. Site assessment results automatically, without manual calculations.

LKK423  Voice Digital Hammer ( Schmidt Hammer ) Main Feature:

1) based on "Hammer testing concrete compressive strength Technical Specification" (JGJ / T23-2011) independent research and development, have complete independent intellectual property rights.
2) one design a national initiative, the organic integration as one of the hosts and Hammer Hammer sensors, without any cables, portable, low failure rate.
3) the first to use true color LCD screen, 176 × 220 resolution, convenience, Chinese interface, operation.
4) The unique voice prompts rebound value without viewing the screen to know rebound value, improve the detection efficiency testing personnel.
5) Hammer sensor uses non-contact metal reflection grating sensors, completely avoiding the use of a potentiometer or other contact methods in sampling methods prone to mechanical wear, poor contact and other defects, and there is a high precision, long life and other characteristics, while retaining the mechanical pointer ruler.
6) can be an external infrared transmission portable printer, on-site inspection report can be generated.
7) high-capacity data storage, can store up to 200 standard components, a standard component can detect up to 99 survey area, fully meet the needs of actual testing work.
8) Built instrument of national unity curve, and increase regional or special curves, replaced at any time by the user, can store up to 20 strength curve.
9) components and field-entry zone parameters measured, and the result is automatically calculated member.
10) function automatically remove outliers, the rebound value set by the user, the lower limit, and the use of screens and voice prompts.
11) using the USB communication port, and a U-disk virtual way, no need to install any drivers, you can export the data or replacing special strength curve.
12) with real-time clock calendar function that automatically detect the recording date and time of each member.
13) advanced low power management features, you can set the screen backlight, voice volume, automatic sleep, and automatic shutdown function, improve the instrument's use of time.
