Strong in durability and wear resistance, ideal for sewage pump stations and manhole pumps!

The 26KyX series water level gauge is a submersible water level gauge specially developed for sewage and wastewater applications. It features a diaphragm made of Kynar with PTFE properties, providing resistance to viscous media along with excellent hardness and abrasion resistance. The 26KyX water level gauge can be easily installed in harsh environments without the need for expensive protective cages that take up space. Measurement results can be obtained via an RS485 interface, as well as through analog signal output via a built-in D/A converter, allowing for scaling settings (modification of the water level range). A version with a built-in lightning protection device is also available (optional). 【Features】 - Anti-fouling diaphragm design - Body material made of SUS316L - RS485 serial communication - Accurate correction technology

It is also possible to measure low water levels of 30cmH2O! There is also an explosion-proof type available.

The water level gauge series 46X is a low-level water gauge that uses a ceramic sensor element, capable of measuring water levels from 0 to 30 cmH2O. By performing mathematical correction processing on a microprocessor digital circuit, it achieves an accuracy of ±0.1% FS. In addition to a digital RS485 interface, it also features an analog output, allowing for scaling settings (changing the water level range). An intrinsically safe explosion-proof type 46XEi is also available. 【Features】 〇 Utilizes a capacitive method. The ceramic sensor element is suitable for low-pressure measurement. 〇 Standard equipped with both digital RS485 and analog outputs. 〇 Digital correction of output signals. 〇 Explosion-proof type available (41XEi).

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who wish to enter, whether on a busy street or in a narrow passageway.
