Ref. Standards IS: 11229, 2720 (Part 13) Operation: Motorised Rates of Strain: 1.25, 0.625, 0.25, 0.125, 0.05, 0.025, (mm/min) 0.01, 0.005, 0.001, 0.0004, 0.0002 Specimen Size: 60x60x25mm. This surcharge weight set comprises of following weights: 0.05kg/cm2: 4Nos. 0.10kg/cm2: 1No. 0.20kg/cm2: 1No. 0.50Kg/cm2: 3Nos. 1.00Kg/cm2: 1No. Compression-Tension Proving Ring, 2kN capacity 1No. Dial Gauge 0-25x0.01mm 2Nos 2 Consolidation Apparatus As per IS:2720 (Part-XV), Should Consolidation Cell Assembly - min 3 Nos Fixed ring with Guide ring— Min 3 Nos Channelled base with water inlet— 3 Nos Water Jacket — 3Nos Different Set of weights Water Tank with assembly 3 Triaxial shear test apparatus Ease of installation and operation. The use of microprocessor controlled drive system and keyboard entry provides the Load frame with a wide variety of features which include pause and speed reset during test, RS232 interface for computer control. Operator programming of speed and control functions, self test diagnostics and many other features. Suitable for operation on 220V, 50Hz single phase, AC supply. Capacity: 50kN, Drive Mechanism: Stepper Motor Drive Microprocessor controlled, Platen speed range: 0.0001 to 9.99999mm/minute. Fate forward & reverse: 10mm/minute, Rapid Approach Speed: 25mm/minute, Horizontal clearance: 364mm, Max. vertical clearance: 910mm Max. Platen travel: 100mm, Specimen dia: 38mm to 100mm, Dimesnsions(LXWXH): 600x500x1440mm, Weight: 85kg(approx.). Triaxial Cell, Stationery Bushing, 38mm dia:- Ref Standard:IS: 2720(Part XII). For testing specimen of size 38mm dia x 76mm long. Constant pressure system oil water type with two cells:- Pressure Capacity, 10 bar (10kg/cm2). This system provides an effective alternative to Mercury and Water Constant Pressure System especially where the laboratory head room is insufficient. The apparatus is designed to provide confining pressure upto 16 bar to Triaxial cells however for safety it has been factory-locked at a max pressure of 12kg/cm2. Range: 10kg/cm2, Resolution: 0.1kg/cm2, Accuracy: +1% of the indicated pressure Environmental Engineering Lab 1 DOUBLE BEAM UV-VIS SPECTROPHOTOMETER TYPE Type of Spectrophotometer: UV - VISIBLE Type of Optical System: Double Beam Monochromator Type: Holographic Grating Detector Type: Photodiode Spectral Bandwidth Type: Fixed Bandwidth LIGHT SOURCE Light Source: Deuterium Lamp Diffraction Grating (lines/mm):1400 Switching of Light Source: Automatic Wavelength Setting and Scanning: Automatic OPTICAL PERFORMANCE Source Wavelength –Minimum: 190 nanometer Source Wavelength –Maximum: 1100 nanometer Resolution: 0.3 nanometer Wavelength Accuracy (+/-): 0.5 nanometer Bandwidth (nm): 0.1 Scanning Speed(nm/min): 300 Focal length (mm): 100 to 149 Photometric measurement modes: Transmittance, Absorbance, Concentration (Wavelength, time) Photometric Absorbance(Max) (Abs) (+/-): 3 Photometric Absorbance Accuracy (Max) (+/-): 0.005 Photometric Transmittance (Max) (+/-): 100 percent Photometric Transmittance Accuracy (Max) (+/-): 0.1 percent Photometric Reflectance (Max) (+/-): 0 percent Photometric Reflectance Accuracy (Max) (+/-): 0.005 percent Baseline Correction: Automatic GENERIC Display: In-built display Display type: LCD with Backlight
