About This Product

Overview

■A quick initial response system in the event of an earthquake is based on capturing accurate seismic intensity information using a measuring seismic intensity meter (seismograph) certified by the Japan Meteorological Agency.

It instantly captures the small vertical shakes (P waves) that occur before a large earthquake occurs, and predicts the large horizontal shakes (S waves) that will arrive afterward to warn of danger. This seismometer can be stored in a dedicated carrying case and easily carried around, and can be used for temporary installation at construction sites, or to protect rescue workers from secondary disasters caused by aftershocks at dangerous recovery sites in earthquake-stricken areas. PS catcher is useful in various scenes. Features

■Portable seismometer

It can be carried around in its own carrying case.

■No special installation work required

Once you transport it to the site and make some simple installation adjustments, you can start observing immediately.

■Meteorological Agency certified product

It has passed the Japan Meteorological Agency certification as a measuring seismic intensity meter.

■Early earthquake detection function

It is equipped with calculation functions based on the earthquake specification estimation algorithm specifications for early warning seismometers (a joint patent of the Railway Technical Research Institute and the Japan Meteorological Agency).

■Speed-up information processing using seismic intensity real calculation method

Calculates seismic intensity in 1 second increments and immediately issues an earthquake warning when S waves arrive. (Our own: Patent No. 3241486)

■Alarm unit with loud revolving light

Immediately alerts you to danger with a loud volume of up to 108dB and a rotating light.

■High-capacity compact flash card (up to 16GB) can be installed

Earthquake information and waveform data can be recorded for long periods of time on compact flash cards. It can be used for data analysis on a computer. (Standard accessories are 256MB)

■Lighter weight

Compared to our conventional product, we achieved a total weight reduction of 14 kg.

■Improved visibility

Visibility outdoors has been improved by using a high-brightness liquid crystal display.

■Improved reliability

The processing section also has a waterproof structure (splash-proof type), making the entire device waterproof.

■Improved maintainability

The battery and watch coin cell no longer need to be replaced for 10 years, improving maintainability.

■Adoption of wireless alarm device

In addition to wired alarm devices, it is also compatible with portable radio devices (Silwatch, Cublight) that can be worn by rescue workers. (optional)
