• X-ray fluorescence analyzer

• Horizontal sample collection • Ideal for water sampling at the lake bottom and in stratification • Made of transparent polycarbonate (011) • Includes drop messenger • Certified polyethylene and silicone by the U.S. Environmental Protection Agency • Suitable for trace metal and trace biological sampling. * An opaque white type and vertical type (transparent and white) are also available.

• Other environmental analysis equipment

• You can select from five different injection volumes by sliding the selection knob. Press down the control knob and rotate the main drum to inject. The injection range starts from 0.25μl with the glass syringe attached. This is a manual micro-injection device with a thin film protective coating finish. The injection volumes of 0.25, 0.5, 1, 2, and 5μl can be quickly and easily selected. • Rotate the syringe adjustment screw to attach/detach the glass syringe.

• Other physicochemical equipment

• Portable and easy-to-operate quantum light meter OSK 12TU179 • Measures the light necessary for plant growth, Photosynthetically Active Radiation (PAR) • Measures the wavelength range of PAR from 400 to 700 nm • Measurement unit: Photon flux density (μmol/m²s) • Measurement range: 0 to 1,999 μmol/m²s • Operates on a 9V battery • Low cosine error (70-50% compared to competitors) Overview The wavelengths of light observable by the naked eye have little impact on plant growth. While Lux or candela indicate the light in the Human Eye region shown in the upper left image (approximately 500-600 nm), the wavelength range of 400-700 nm, which is Photosynthetically Active Radiation, includes light quantities in the wavelength band that significantly affect plant growth. By measuring photon flux, it becomes possible to assess and quantify whether plants are receiving sufficient light necessary for their growth. What is light? Wavelength: Light is electromagnetic radiation. Wavelength is expressed in nanometers (nm). Particles: Light consists of photons, which are quanta. Each photon possesses a small amount of energy, and photons are measured in moles (mol), with 1 mol equaling 6.02 x 10²³ photons. μmol is one millionth of a mol.

• Other measurement, recording and measuring instruments

This is a device that can accurately measure the specific gravity of mud water easily on-site. Made of zinc-aluminum alloy, it features a strong and durable structure, as well as excellent uniformity. The rod section is marked with four types of scales (g/cm3, lb/gal, lbs/ft3, lbs/in2/1000 ft), which are precise and easy to read due to laser processing. Furthermore, the surface of the rod is smooth due to anodizing, making it easy to clean and enhancing its corrosion resistance.

• Other measurement, recording and measuring instruments

• Microprocessor PID control • Three models with capacities of 6L, 11L, and 22L • Corrosion-resistant stainless steel oil tank

• Thermostatic water bath

Precise temperature control using digital PID control Up to three frequently used temperature settings can be saved (with preset function)

• Thermostatic water bath

This machine, while compact and lightweight, can accommodate sieves of φ200 and φ203mm through digital control operation. <Features> This machine adopts the latest technology for high accuracy and reliability. High performance is achieved through three-dimensional motion of vertical vibration and horizontal rotation. A sample density of 0.8g/cm³ or higher is recommended. It is compatible with both dry and wet sieving. The maximum amplitude can be changed from 2.00mm to 0.5mm in increments of 0.1mm.

• Other physicochemical equipment

• This device measures the skid resistance of paved surfaces. It is suitable for both field and laboratory use. • It is also possible to measure the PSV value (Polished Stone Value). In this case, curved samples obtained from the accelerated polishing test (in accordance with EN 1097-8) are used. Additionally, tests can be conducted on paving stones (EN 1341, EN 1342) and paving blocks (EN 1338). • This device was developed by the Transport Research Laboratory in the UK and consists of an adjustable pendulum and a rubber slider attached to the tip (see accessories). The test is conducted by lifting the pendulum horizontally, releasing the lock, and allowing it to fall, while the tip of the rubber slider is slid over the pavement or sample surface.
